Gear Review: CompMag California Compliant AR-15 Magazine ...
Give your AR-15 a fixed, 10-round magazine. If it doesn’t detach or hold more than 10 rounds, you’re in the clear. (Makes sense, right? Don’t answer that.) So, that’s exactly what CompMag did. The way it works is simple. Remove your upper receiver and insert the CompMag in your magwell. Next, put the supplied plate over the screw hole in the mag.
