The DROP STOP is a simple mechanism that prevents your upper receiver from dropping open when the rear takedown pin is removed. It works in conjunction with all California conversion kits – the Cross Armory Safe Mag, the Patriot and the AR Maglock. The DROP STOP will easily mount to Picatinny, M-Lok and KeyMod rail systems.
