If you are an AK owner who wants to add an optic without using a side rail, the LithocoreX Adaptive System for AK – AKARS is worthy of consideration. If you don’t have a side rail on your rifle and want an optic, getting this part is even more important! You can mount an optic on certain fore grips but I find placing an optic closer to my eye preferable. It also keeps the front end from getting too top heavy.
There are several of these types of systems on the market but LithocoreX is definitely one of the best. It’s essentially a dust cover with a 1913 Picatinny Rail as placed securely on top. It allows you to retain zero after firing and field stripping.
Built in is a rear sight which also allows for the user to use as an iron sight should the mounted optic fail, or if you simply want to shoot sans optic.
