The AR-15 extended bolt catch gives shooters a larger, easier-to-reach surface for locking and releasing the bolt. Builders install it on the lower receiver in place of the standard bolt catch. Shooters press the enlarged paddle to lock the bolt open or release it with a quick tap. The extended design works well for those who prefer faster bolt manipulation during drills and range sessions. It fits standard AR-15 lower receivers without modification. An AR-15 extended bolt catch improves control and speed during bolt release operations.
