The Circle 10 AK 2-Bolt Triangle Stock is a product that was designed and manufactured for 10-32 side folding adapters. It’s a tad bit shorter to make up for the extra length side fold hinges add to the length of your rifle. This particular item is milled from billet 6061 aluminum and has an anodized finish. It will utilize standard 10-32 hardware and can be bolted onto any compatible hinge such as Stormwerkz. Includes 2 QD (rotational) mounting points, 1 on each side. The length of the stock is 6.5″ and weight is 13.8oz. (The older Ace hinges are compatible with this but the new ones are not).
