UTG PRO AK Side Folding Stock for Yugo Pattern Receivers - Black - RBU47FS02 - UPC 4717385557543
Product Description
The UTG PRO AK Side Folding Stock (RBU47FS02) is an American-made, high-strength tactical stock upgrade engineered specifically for Yugo/Zastava pattern AK rifles. Designed to mount directly to Yugoslavian pattern rear trunnions without requiring permanent modifications, gunsmithing, or secondary adapters, this glass-fiber reinforced polymer stock provides superior ergonomics, modularity, and compact storage capabilities for heavy-duty AK platforms.
A key highlights of the RBU47FS02 is its right-side folding mechanism. By folding to the right side of the receiver, the stock maintains full clearance for side-mounted scope rails and optics adapters, allowing shooters to fold and transport their rifle without removing primary optics or optical mounts. The robust spring-loaded locking hinge deploys quickly and locks solidly in both the extended and folded positions via a push-button mechanism.
Built for custom ergonomics, the stock features a 5-position adjustable Length of Pull (LOP) ranging from 13.59" to 16.42" in 0.71" increments to accommodate varied shooter sizes and body armor profiles. An angled, non-slip rubberized buttpad cushions heavy 7.62x39mm recoil and firmly anchors the stock in the shoulder pocket, while integrated front and rear Quick-Detach (QD) sling swivel housing points allow full sling attachment versatility. Proudly made in the USA, this stock counts as one U.S.-made compliance part under 18 U.S.C. § 922(r).
