Wilson Combat Super-Stoc Carbine Buttstock is a collapsible tactical stock engineered for AR-15 pattern carbines. Constructed from high-strength black synthetic polymer, it features an innovative Cam-Lock System that eliminates slop or play on the buffer tube. Clicking the cam-lock lever upward locks the stock securely, while the quick-release lever disengages both the cam-lock and detent pin for rapid position adjustments. Dual-compatible with both Mil-Spec and Commercial-spec buffer tubes. Buffer tube not included. Total weight measures 7.30 oz. Safety note Follow all manufacturer installation instructions. Verify proper function and secure mounting before use. Comply with local firearm laws and regulations.
