Whether you intend to use it for a temporary trial or as a permanent installation, the Strike Industries Stock Stop effectively adapts your existing convertible stock to function as a single position, AR fixed stock.

Strike Industries Stock Stop: Simple Installation, Widespread Compatibility

The Strike Industries Stock Stop is an easy to use stock stop that allows the user to convert virtually any multi-position stock and receiver extension combination into a fixed position stock. It’s simple to use, made of high-quality TPU-85A thermoplastic polyurethane and works well with 6-position aftermarket tubes or Strike’s own 7-Position Receiver Extension. Just cut the SI Stock Stop to the appropriate length for your application, leaving only the final extension available, drop it in and you’re ready to go. The Stock Stop won’t allow further adjustment of your stock and is designed to remain in place without drawing attention to itself. There is no need to drill holes in your stock and place a permanent pin to recreate your adjustable stock as a fixed unit.
