CAA AKSFSA 6 Position Buffer Tube for 5.5mm AK100/74 & Saiga Hinges

Turn your side-folder AK into a collapsible, AR-style shooter without giving up the fold. The CAA AKSFSA bolts to any 5.5 mm AK100-series, AK-74M or Saiga hinge and replaces the factory tube with a rigid 6061-T6 aluminum, 6-position buffer tube that accepts every mil-spec M4/AR-15 stock on the market. At just ≈ 7.4″ long, 29.5 mm (1.17″) diameter and ~9.7 oz of anodized alloy, it locks up rock-solid, keeps the rifle’s folding mechanism intact, and lets you dial length-of-pull for armor, winter gear or smaller shooters. No gunsmithing—just drive out the hinge pin, drop the AKSFSA in, tighten the captive screws and start shouldering a stock that actually fits you. The result is tighter groups, quicker target transitions and far better ergonomics than any surplus wood or polymer folder can offer.
