The Strike Industries AR MAGSTOP (5-pack) offers a legal storage only solution to conform your AR-15 and/or AR-10 to state compliance law. The AR MAGSTOP is a cost-effective way to convert your AR to a fixed magazine configuration. Remove your existing magazine release button, remove the magazine release spring and then install the AR MAGSTOP all the way in the lower receiver and over the magazine catch threads. Once correctly installed, there will be a small wobble but you will not be able to release your inserted 10-round magazine. When you are no longer storing your AR, the SI AR MAGSTOP can easily be removed with a punch and reconfigured for live fire. Tested to be compatible with most magazine catches currently on the market including the Strike Magazine Catch. The Strike Industries AR MAGSTOP is a one-time use product. If your state laws require compliance, don't get caught with your pants down and have your AR legally stored in your safe when not in use. FeaturesConfigure you...
