Advice for those who plan to upgrade

Before you modifying or consider an AK-47 upgrade, consider a few words of advice:

Whatever aftermarket AK-47 part you acquire, be aware that it may not always fit.

Sound strange?

Welcome to the AK universe.

Among the spectrum of Kalashnikov variants, there is no universal, Mil-Spec standard. From an American perspective this may seem odd, but it can be understood by considering the rifle’s genesis.

Though the Soviets demanded that Warsaw Pact constituents adopt the AK-47 as their military rifle, they allowed members to purchase them from either the Soviet Union or license and manufacture their own AK rifles. (Czechs were exempt for many reasons and instead of the AK fielded their own homegrown assault rifle, the Samopal vz. 58.)

The Soviets weren’t concerned about parts interchangeability with variants of different origins. They only required that the rifles all be of the same design and that they use the same magazines, the same standard 7.62×39 cartridges and the same manual of arms. Thus a Romanian soldier should be able to pick up and use an AK made in Hungary, East Germany, Russia, Bulgaria, etc., with equal facility.

This converted Saiga includes (from left to right) an LMT SOPMOD buttstock, Rifle Dynamics adapter, TAPCO pistol grip, TAPCO G-2 trigger, Krebs Custom safety, Circle 10 magazine, Circle 10 AK U-Notch rear sight, K-VAR polymer handguard set, Blue Force Gear Vickers sling, DPH Arms retainer, RazorSix Tactical WIKQD Mount and Venom Tactical ‘Antidote’ muzzle brake.

The AK platform, in effect, became “Balkanized.” Every country (including many outside the old Soviet Bloc) produced its own slight variation on the theme. Whether

Serbian or Israeli, the specs, such as the thickness of the receiver, type of stock, etc., might be slightly different.

With this in mind, Jim Fuller, founder of Rifle Dynamics, once quipped that gunsmithing an AK is more akin to “blacksmithing.” What he meant was that building an AK always entailed modifying parts to make them fit. That may mean taking sandpaper, a file or even a dremel to the parts in question.

So why should the buyer be aware of this?

Although the average user will mostly likely not build an AK from the ground up, chances are he or she will add aftermarket parts. For that reason, it’s good to be cognizant of Fuller’s admonition about AK-47 upgrades.

The rule of thumb is that any part you add to your rifle may entail slight modification. This video from UltiMAK which illustrates how to install an Arsenal lower handguard in conjunction with their M1-B optic mount depicts typical modifications demanded when adding third party parts.

Safety lever Upgrade

November 9, 2016 By Robert Kay

The humble safety lever is usually not high on the customization list for neophytes, but it should be.

I suggest you consider swapping out your stock safety lever for a Krebs Custom model. The Krebs products are an enhancement of the original part because they help the shooter perform a simple but extremely important task —taking full control of the operation of the safety lever. The design allows for continuous finger contact throughout the entire range of motion.

The extended shelf on the lever is ergonomically correct and easy to operate. You can flip the safety with your trigger finger while keeping the shooting hand firmly around the pistol grip.

The location and shape of the lever, a distinct curve, allows the finger to instantly return to the trigger in one fell swoop.

You’re not going to be distracted or lose your sight-picture, even when using an optic.

Another innovation not immediately noticeable to the novice is a bolt hold-open (aka BHO) slot on the lever. The BHO catch allows the operator to easily keep the bolt open so that the range officer can observe whether there’s a round in the chamber.

the-krebs-mark-vii-ambi
The Krebs Mark VII Ambi Enhanced Safety allows righties to manipulate the lever with the index finger and lefties with their thumb. (Robert Kay)

For years the standard replacement for the stock safety was his Mk VI series ($59), which Krebs designed for Russian-pattern milled and stamped receivers.

The newest addition to the Krebs line is the Mk VII “Ambi Enhanced Safety” ($65.00) made for both left- and right-handed shooters.

Right-handed shooters can manipulate the safety with their index finger and lefties can do so with their thumb.

Quality and finish are first-class on all models. The coating is a durable, smooth matte. The good news is that you don’t have to pay a gunsmith to swap out your safely. Even if you’re a rank amateur, they are easy to install. Simply remove the recoil spring and rotate the old safety toward you. At a certain point, it will pop out of the hole in the receiver. Put the new one exactly where the old one was and rotate in the opposite direction (down). The recoil spring goes in, as does the dust cover. Bingo, you’re done.

In addition to the Krebs Custom series, I’ve heard good things about the R&R Targets safety. The caveat is that it’s not a drop-in. Your gunsmith will have to do some tweaking.

AK Trigger Upgrade

November 9, 2016 By Robert Kay

An AK trigger upgrade may be in your future. Although the standard trigger system (aka fire control group) is decent, with some modifications can be an excellent trigger. The modifications entail smoothing out a few rough edges on the hammer. If you’re interested in researching this, there are number of videos on this subject. R&R Targets has developed a good trigger based on the Tapco.

A better option is to purchase the AKT-EL trigger system from ALG, a subsidiary of Geissele, a company renowned for excellent AR 15 (and other rifle) triggers. (I own an AKT-EL system and love it). The standard version is priced under $65. You can also get the enhanced AKT-UL version which competition shooters will dig.  Krebs Custom also has an excellent trigger modified from the Geissele.

alg-defense-ak-trigger-r-161

Instead of taking a file or sandpaper to the trigger, another option is to swap out the fire control group. There are some good videos that will show you, step by step, how to do so. Changing out your FCG is not an inordinately difficult task for someone who has a modicum of mechanical skills and common sense.

Why would you want to replace a decent trigger in the first place?

Some folks, especially those who have owned rifles or 1911 pistols with good triggers are simply fussy. Or they may want their AK to have a quick reset for rapid fire.

There are any number of reasons but it comes down to an individual’s specific needs or desires.

AKT-UL (Enhanced) features a lighter and crisper break than the standard AKT Trigger, making it ideal for precision shooting

Unlike some trigger sets for the AR, most AK triggers are not adjustable. One exception is the model from Red Star Arms, which can be adjusted as a one or two-stage affair.

A company called CMC Triggers  has a new drop-in style model specifically for the AK. It’s the first decent modular trigger for the AK that I’ve tested.

The only word of caution, and this goes for installing any third-party part in an AK, is be certain that the trigger you acquire will work precisely with your AK.

I installed a Red Star Arms trigger on a VEPR and eventually got it working, but it was a real chore to do so, meaning we had to take dremel and do quite a bit of grinding on the safety. This is not something for the beginner.

The Joys of Trigger Slap

Another reason to install a new trigger is if after you purchase your gun you experience “trigger slap.”

Trigger slap is a common occurrence in AKs. You’ll certainly know it when you feel it.

trigger-slap-afflicts-many-an-ak
Trigger slap afflicts many an AK. This illustration by Rick Davis shows how force from the bolt carrier transfers to the trigger. It can be resolved.

Trigger slap is the stinging sensation of the trigger springing back or “slapping” the shooter’s trigger finger during firing.

It’s a sharp, unambiguous jolt that can occur with every shot or intermittently, sometimes favoring a particular type of ammunition. It’s often misdiagnosed as an ammo problem.

It can be mitigated by changing out the trigger, or you can have a gunsmith or someone very familiar with an AK fire-control group fix it.

It’s caused, says AK maven Rick Davis, when there’s insufficient clearance between the hammer, trigger and the disconnector. When this happens, the force of the resetting hammer is transferred into the trigger through the disconnector, causing the trigger to abruptly “slap” forward.

Says Davis:

“If there’s too much material on the rear disconnector pad, it will lack adequate clearance between the bolt carrier, disconnector and trigger. This results in a chain collision between the bolt carrier, disconnector and the trigger. The energy is then transferred into the shooter’s finger, producing the ‘slap’ sensation.

removing-material-from-the-red-area
Removing material from the red area helps correct trigger slap. (Courtesy Rick Davis).

He says this can be corrected by removing just enough material on the rear of the disconnector near the spring well. Remove only enough to allow proper clearance, no more.

Lyle Keeney, founder of UltiMAK, has a slightly different take on the matter. Says Keeney:

“The only cause I’ve seen was that the camming angles between the hammer and the disconnector were such that the disconnector was being accelerated backward so violently that no amount of clearance would solve the slap. Only by reshaping the camming angles between hammer and disconnector, providing a more gentle rearward motion of the disconnector, was the slap eliminated entirely.”

Keeney states that it’s easy to check for adequate (disconnector-to-trigger) clearance by holding the trigger all the way back as you slowly pull the carrier back to cock the piece, or simply cock the hammer by manipulating it directly with the carrier removed.

If the trigger is not forced forward at all while cocking the disconnector over the hammer, you probably have enough clearance, and should therefore look elsewhere to solve the slap issue.

As alluded to above, if you’re not experienced, correcting trigger slap may not be a task you want to attempt.

However, smoothing out a gritty trigger is do-able, if you’re not aggressive about removing too much metal.

There are a number of videos that will show you how to smooth out the action by applying a little sandpaper or emery cloth. Graham Baates does a nice job with this video.

AK Minimalism—Lessons from Larry Vickers

November 9, 2016 By Robert Kay

When it comes to adding handguards and other accessories, less can be more. Like many first-time AK buyers, when I got my rifle I started adding third-party parts and went overboard on the “tacticool.” This included items such as a full-length handguard, optics, fore grips, scope mounts and the like. Before I knew it, I was drowning in paraphernalia.

The lesson was that adding some of these components may make sense in some circumstances, such as home defense, but you need to be wary of “mission creep”. Loading up your rifle with gewgaws has its practical limits. For example, if you’re going to be proficient at shooting offhand, shouldering a 10-pound rifle gets old very quickly.

(My epiphany is hardly original. One of Larry Vickers’ maxims is “seriously resist the urge to over-accessorize the gun”.)

Given my own experience, I’ve become a proponent of minimalism.

ac-15

Custom builders such as Rifle Dynamics, Krebs Custom, Definitive Arms and others strive to keep the weight down by using a combination of polymer furniture (often from Arsenal) and in some instances, even chopping the barrel two inches.

Jim Fuller of Rifle Dynamics takes the weight reduction process a step further by employing the Bolton Gas Block, a proprietary product manufactured by Venom Tactical.

This cleverly designed product is the latest incarnation of a technology used by the Israeli Galil, the Finnish Valmet RK62 and other rifles, combines both the front sight and gas block into a single assembly. The system allows you to remove the stock front sight block, which diminishes weight on the front end of the AK47/74 and makes handling the rifle easier. (According to Lenny Bolton, the founder of the company, these gas blocks have been proven reliable in combat conditions).

The Bolton Block, designed by Venom Tactical, combines a gas block with a front sight. Additional weight savings on this rifle come from a shortened barrel and an UltiMAK M1-B optics mount. (Courtesy Rifle Dynamics)

By placing the front sight atop the gas block, the barrel length can be shortened. Jim Fuller has integrated this system on many of his high end rifles. He says that with the proprietary gas block and a shortened barrel, he can take off as much as a pound from the front end. It doesn’t sound like a lot but in practice it’s very significant.

Lenny Bolton states that the shorter sight radius on his gas block/front sight provides faster target engagement. While losing a few inches of sight radius might concern some people, he says that it’s not an issue if you’re going to engage a target under 300 yards. The front sight is adjustable for windage with a simple screwdriver.

Bolton has sold thousands of the $99 gas blocks. However, he suggests that people without extensive experience should let a gunsmith install the part. If you’re interested in researching how to do it, this article in Rifleshooter.com will illustrate how.

If you’re going to use an optic on your minimalist rifle, there are ways to keep the weight down. Jim Fuller of Rifle Dynamics employs the UltiMAK M1-B optic mount on some of his AKs. This $98 product integrates both the handguard and the gas tube in its design which ends up adding less than an ounce to the rifle.

Lyle Keeney of UltiMAK says that a lightweight red dot atop the rail brings a great deal more “shootability” to a rifle without adding significant weight. It’s still a “minimalist” setup, he insists and is mandatory if you shoot at moving targets, in low light, or at targets of opportunity (requiring fast targeting on short notice).

You can get a wide variety of lightweight polymer handguard sets from K-Var. Their typical upper handguard is simply a U-shaped section of plastic which covers the gas tube. (Note that the gas tube must have a bracket to retain it). If your gas tube doesn’t have one, you can buy an entire assembly (upper handguard plus gas tube) for about $45. Keep in mind that there’s no rail atop this system so if you want to add an optic at a later date, you’ll need to pick up a side mount.

heat-shield
This lower handguard from Arsenal is super light (4.1 oz.) and has a stainless steel heat shield. (Robert Kay)

The second part of the equation is the lower handguard. K-VAR sells a variety of them from $23-75. All have a stainless steel heat shield. To add it, simply slip the rear end into the receiver and cinch down the opposite side with a special retainer ring or bracket.

There are two styles of retainers.

To keep a traditional look, you can purchase the standard-issue retainer ring from K-VAR for $30. It’s very solid and has a lever, similar to that on the rear sight block, to keep the lower handguard firmly affixed to the barrel. The only caveat is that with this particular setup you’ll have to remove the gas block and the front sight block from the rifle in order to install it. Removing both these parts takes special tools and is best left to a gunsmith.

If you want to keep your rifle as close to original as possible, this is the best way to go.

The handguard retainer ring at left is original equipment for Arsenal and other variants. It’s secured with a lever (visible on the upper left). DPH Arms manufactures a two-piece retainer which is fastened with bolts and can be installed without removing the gas and sight blocks. (Robert Kay)

If you don’t want to go through the hassle of removing the above-mentioned parts, there’s a second style of retainer ring which consists of two pieces.

There are at least three small companies that make these parts. One of the manufacturers, DPH Arms, has a set screw in the center of their retainer ring to help keep it from shifting. It also has shims so that the same unit can be used on a standard AK or taken off so that the retainer can be used on the larger diameter VEPR barrel.

Generally, adding the retainer shouldn’t take any modifications to the handguard. However, Brian Smithwick of Dinzag Arms (which also manufactures retainers) suggests you create a small bulge on the heat shield with a pair of needle nose pliers if you have an AK-74. This protuberance will position the handguard off the barrel and underpin the fit to prevent the AK-74 handguard from sliding up at the front end of the retainer plate.

To install the retainer from Saiga-AK, one must add a notch or divot on the barrel keep the bracket in place.

I didn’t want to adulterate my barrel, nor remove the gas and front site blocks so I decided to go the DPH Arms route. If you are a stickler for detail, professional builders suggest that you use the original equipment retainer from Arsenal but if you don’t have the tools to remove the parts, the two-part brackets will do the trick. The DPH product retails for $44.99 and worked fine.

Both brackets feature a sling mount loop and a hole that secures the end of the cleaning rod. UltiMAK founder Lyle Keeney suggests that if you have a cleaning rod mounted below the barrel you consider removing it to reduced weight. If you need to clean your rifle in the field you can take a bore snake with you.

There’s third type of aluminum retainer available but I would not recommend it. It’s very easy to strip the threads on this item. You’ll want to make sure and purchase a retainer manufactured from steel.

Although the polymer handguards from Arsenal (or similar units made by other manufacturers), are great at keeping the weight down, a KeyMod handguard system is also an option if you feel it’s absolutely necessary to add other accessories, such as a light or a grip to your rifle.

the-ak-ufm-keymod-lower-handguard
The AK-UFM KeyMod lower handguard from Krebs Custom is only 6.6 oz., including the add-on Picatinny rail. (Robert Kay)

KeyMod handguards, such as the AK-UFM model for AKM rifles manufactured by Krebs Custom, are made from aircraft aluminum and they are really light. At 6.6 ounces (including the Picatinny rail) it definitely falls into the “minimalist” camp.

Another weight saving measure is to change out your buttstock if you’re using a collapsible, AR 15-style system. There are a number of lightweight units available including the Rogers Super-Stoc, the Mission First Tactical “Minimalist” model and the CTR from Magpul. In this chapter (see section below) I’ve reviewed these products and other options that are both comfortable, and lightweight.

The lesson is to think twice before you buying add-ons, such as a full-blown tactical handguard/rail system. If you can eschew adding stuff that you don’t really need, or replace your existing gear with something lighter, by all means do so.

With AKs less is always more.

Magazines

November 9, 2016 By Robert Kay

The AK rifle has a well-deserved reputation for reliability. Making sure the weapon would fire upon demand under trying battlefield conditions, first time and every time, was one of the primary goals of the engineering team responsible for the design, development, and production of the AK-47. However, any rifle (or any machine for that matter) is only as reliable as its least dependable part. In the case of self-loading rifles, the device responsible for feeding ammunition to the breech mechanism is critical.

That part is called a magazine — not a clip, which in technical firearm terms is something different.

If the magazine assembly is faulty or poorly designed, the rifle cannot be relied upon to feed ammunition properly.

At the range or local plinking area, feeding malfunctions can be frustrating and lead to potentially dangerous conditions within the rifle. In a self-defense situation, they can cost you everything.

There’s a vast array of magazines available for the AK today. Capacities range from two- or three-round box magazines meant for hunting, to drums that will hold 75 rounds or more. Originally made from steel, they also can be found with bodies made entirely from synthetics (various types of plastic) or a mixture of synthetics plus steel reinforcing at critical points, such as the front and rear locking lugs and the feed lips.

Regardless of body type, all magazines are supplied with springs made of steel. Nobody to date has managed to come up with a strong, durable, reliable spring made of polymer.

The classic Russian Bakelite magazines add a realistic, old world touch to your rifle.

By far the most ubiquitous AK magazines worldwide are the familiar, curved banana-type designed by the Soviets and issued to Warsaw Pact forces as standard military equipment. Each standard AK magazine holds 30 rounds of ammunition. Originally mass-produced by various manufacturers in Eastern Europe, the classic 30-round AK box magazine is robustly built of steel, almost bullet-proof and, like the AK itself, relentlessly reliable.

They are also heavy, anywhere from 11 to 14 ounces empty, depending on the maker. By way of comparison, a standard 30-round aluminum M16 magazine weighs in at about 4 ounces, empty. A steel AK magazine loaded with 30 rounds of military ball ammunition weighs close to 2 pounds, which is quite a load of ballast to add to your AK for casual shooting offhand.

Russian slabside magazines are virtually indestructible.

By far the best are military surplus magazines. They were built with reliability and durability in mind, and for use under the most adverse conditions imaginable. You can find them from a variety of suppliers, in any condition, from old rust-buckets with dents and sometimes even bullet holes, to unissued as-new condition. Surplus military magazines in good condition are probably your safest bet, and come in steel and synthetic versions.

A tip: If you’re buying surplus, avoid magazines with dents. They can cause feeding problems. Rusty magazines are not desirable unless you like do-it-yourself cleanup and repair projects, assuming the rust is just a mild surface feature. Avoid magazines with deep pits or extensive damage inside and out.

Steel magazines can be found in many capacities, not just the 30-round variety. One of our personal favorites is the Hungarian 20-round steel magazine, though they are not easy to locate. (A good alternative  is the 20-round Tanker from Bad Element). Commercial five- and 10-round steel magazines are out there as well, but can likewise be difficult to find and are considerably more expensive than the ex-military 30-rounders. For example the Russian surplus is the best but it is a bit more pricey.

The class was part of a three-week program that teaches candidates basic policing procedures, weapons handling and other skills necessary to protect and defend Afghan citizens. (U.S. Navy photo by Mass Communication Specialist 1st Class David Frech)

One note regarding the purchase of surplus steel magazines.

As alluded to above, good quality surplus is a great option. However, the operative phrase is “good quality”. Demand for high quality surplus mags has skyrocketed but the supply has diminished. The issue with anything used is that there may be problems with some of them functioning properly.

The 30-round Korean KCI Magazine is more than adequate for range work and self-defense.

The lesson is that it may be in your enlightened self interest to purchase new production steel magazines because it’s guaranteed that they will work, and if they don’t, you’ll get your money back or will be able to exchange them. This may not be the case with a used magazine. For new production steel magazines on a budget check out the Korean KCI Magazines. If you have a little more discretionary funds, the new production Romanian steel magazines are the best that you can buy.

Synthetic magazines have become increasingly common over the years, to the point where in the U.S. they are now at least as readily available as steel. Made by a variety of manufactures from a wide array of different types of plastic, they are lighter than steel, will not rust or dent, and can be had in a range of colors. Some of the best include the military surplus Soviet Bakelite-style, and Bulgarian “Circle 10” polymer magazines, both of which feature steel reinforcing at critical points.

imported-from-bulgaria
Imported from Bulgaria by Arsenal, this Circle 10 polymer magazine is easily recognized  from its “waffle” motif and the number 10 stamp inside the circle at the bottom. Priced at $45, it’s considered one of the best. (Robert Kay)

The Circle 10, which I’ve had a chance to use, is utterly reliable and has almost no play or wobble once inserted in the magazine well. This brand is easily recognized by their logo, the number 10 stamped inside a circle and the magazine’s waffle-patterned body. Priced at around $45, they are not cheap but it’s a question of getting what you pay for.

If you’re just plinking at the range, this inexpensive Tapco magazine will serve you well.

Steel reinforcing is especially desirable in magazines that will see a lot of heavy use or will be employed for self-defense, because the steel helps ensure that the critical parts will be less prone to failure due to wear and physical abuse.

Surplus magazines from Poland or Romania are a great bargain and can be purchased for as little as $15,00

Synthetic magazines are also commonly encountered without steel reinforcing elements, but most regard such as only suitable for casual range or plinking use.

I have used such magazines as supplied by U.S. companies Tapco, U.S. Palm, Pro-Mag and Magpul, and all performed well.

Every nation that builds AKs also builds magazines exclusively for their rifles. Generally, any military-surplus magazine in 7.62×39 or 5.45×39 will work in any standard AK of the corresponding caliber. But as we have seen with other AK parts, there can be exceptions. You may well have to experiment a bit to find out if a particular type of magazine is acceptable to your AK and its unique pedigree.

Choosing a magazine

A candidate AK magazine should be tested for fit. Make sure that both the rifle and the magazine are unloaded, and that the rifle is on safe with the muzzle pointed in a safe direction. The magazine should slide in to the magazine well on the rifle with a firm feel. The front lug should engage the front of the magazine well easily.

note-the-cheek-weld-displayed
Some magazines have “see-through” capability. Note the cheek weld displayed by the venerable Mrgunsngear. (Courtesy Mrgunsngear)

Rocking the magazine back into place, there should be a solid click as the rear magazine latch on the rifle engages the magazine locking tab on the rear of the magazine. There should be no or very little wobble of the magazine from side to side, and none from front to back.There will be some slight variation in fit for magazines of the same model and manufacturer, but it will be slight.

If several examples of the same type of empty magazine won’t lock firmly into place as described, you’d better try another make of magazine for your AK.

Once you’ve determined that they fit, take your candidate magazines to the range with your rifle. Nothing will substitute for running each of the magazines in the rifle in live fire to make sure everything operates correctly and reliably.

VEPR mags are not interchangeable with AKs so you’ll need to stock up on them separately.

If you do any research on the subject, you will find a wide range of opinion as to which magazines you should absolutely avoid purchasing. Yes, there are some real lemons out there. Some of them are even made by companies that manage to produce perfectly acceptable military magazines for other types of rifles, so be careful.

For example, many of the steel magazines made in South Korea are widely regarded as cheaply made and unreliable. Avoiding them might be a good idea.

Others report that they have had trouble with some makes of U.S. polymer magazines.

In the end, as with most things, you are best served by reading the various reviews and opinions and drawing your own conclusions.

The P-Mag from Magpul is a good, inexpensive item perfect for the range

And always do your own tests with a new magazine before you trust your well-being to it.

For our critical applications, we prefer to stick to magazines made by the same manufacturer as the rifle. It’s the safest bet.

Bolt-Hold-Open (BHO) Magazines

Anyone familiar with the AR platform knows that when you’ve expended your last round, the bolt remains open.  It’s always nice to know you’re out of ammo, and for safety’s sake you can visually check whether there’s a round in the chamber.

A standard AK does not have this feature, but you can go to a gunsmith who will be able to engineer a bolt-open solution.

Marc Krebs of Krebs Custom suggests that although A BHO follower is good for range or target work, it’s not optimal in situations where magazine changes must be done quickly.

SGM Tactical, a company out of Knoxville, Tennessee, manufactures bolt-hold-open magazines in .308, 7.62 and 223. It is one of the few companies that makes gear specifically for the VEPR as well as other AKs. I’ve been using its 7.62 BHO mag for about a year with a Saiga, and it works perfectly. Price is $34.95.

Option B is to add a bolt-open-feature to your own magazine by installing a special follower.

mags
This is a bolt-hold-open magazine from SGM (front) and WeaponTech Follower installed (rear). (Robert Kay)

A company called WeaponTech offers a drop-in replacement for standard AK47 metal and polymer magazines designed for 7.62×39.

WeaponTech is a venture between the inventor, Dimitri Mikroulis, and Primary Arms. Called the “WeaponTech BHO Follower,” you will need to disassemble your magazine to install it.

To do this, you take off the magazine’s floor plate, remove the spring, take out the original follower and add the new one designed by Dimitri. It’s not difficult — there are a number of videos that will show you how disassemble a magazine.

The main thing to watch out for is the spring inside the magazine. It’s under a lot of tension and it can pop out and impale your eye, if you’re not careful. Safety glasses are a good idea. Anyone who has taken apart a magazine will understand what I mean.

You can get a three-pack for $14.95. I think it’s a great product.

One last point to remember with a BHO magazine:

When you remove the magazine from the rifle, the bolt will snap shut, as it normally would after the firing cycle is complete.

I forgot that once and got a painful reminder as the bolt pinched my finger.
