Midwest Industries® Side-Folding Light Weight Stock - Fits 1913 Picatinny Rail Endplates, Skeletonized Aircraft Aluminum Body, Heavy-Duty Steel Folding Hinge, Integrated QD Sling Socket, Black Finish - MI-STAP-SF-LWS / 812102033332
Product Description
Modern firearms like the SIG MCX/MPX, Ruger LC Carbine, CZ Scorpion EVO, and AK pistols fitted with rear Picatinny rail adapters offer compact versatility, but finding a rigid, ultra-lightweight stock that folds flat can be tricky. Many folding stock options are bulky, add unnecessary weight, or use weak polymer hinges that wear out under hard operational use. The **Midwest Industries Side Folder with Light Weight Stock - Black, Fits Picatinny Rail (MI-STAP-SF-LWS / 812102033332)** provides a rock-solid, skeletonized aluminum stock designed specifically for 1913 Picatinny rear rail interfaces.
Precision CNC-machined from 6061-T6 aircraft-grade aluminum with a hardcoat anodized black finish, the MI-STAP-SF-LWS features extensive lightening cutouts to keep weight under 10 ounces while maintaining high structural rigidity. It incorporates a heavy-duty steel folding hinge that locks up tight in the deployed position and folds cleanly to the side for compact transport or storage. Complete with a curved polymer buttpad for comfortable shoulder placement and an integrated QD sling swivel socket, this folding stock delivers exceptional performance for modern rifle and carbine builds.
Designed for universal compatibility with rear 1913 Picatinny rail adapters, this lightweight side-folding stock provides rock-solid lockup and streamlined staging directly from your armorer workbench.
*Armorer Bench Notes & Real-World Staging Guidance: The Midwest Industries MI-STAP-SF-LWS stock comes fully assembled and ready for 1913 rail attachment. FIREARM & ADAPTER FITMENT MATRIX: Clamps to any standard **1913 Picatinny rear rail endplate** (found on SIG MCX/MPX, AK Picatinny stock adapters, CZ Scorpion 1913 adapters, MP5 1913 endplates, and BRN-180 lower receivers). Workbench Setup Steps: 1. Always verify your firearm is completely clear of live ammunition with the chamber checked empty before starting installation. 2. Loosen the Torx clamping bolt on the heavy-duty steel hinge base. 3. Align the mounting clamp with your firearm's rear 1913 Picatinny rail at your desired height. 4. Torque the steel mounting bolt to 25-30 in-lbs to ensure a rock-solid, non-slip rail attachment. 5. Test the spring-loaded folding hinge mechanism by lifting up on the stock bar to fold it to the side, then snap it back into the deployed position to confirm positive lockup.*
