Fun video from Brownells about their magazine testing. The closed captioning is funny. But I have to wonder how many M16/M4 barrels and gas tubes they end up melting:
These are the civilians magazines they sell being tested. I’m told the actual military magazines are very tightly controlled from factory through deployment. But rumor has it a few of the tan follower military mags have appeared in the wild, which were absconded from military bases. I wouldn’t suggest buying one, because I’m pretty sure it’s some kind of felony or another to buy stolen federal property.
