Thermold Twin Magazine Lock for 20rd M-16/AR-15 Black Bag

Every magazine has passed the U.S. military’s drop test and survived a few tests of our own. We’ve driven over them with full-sized trucks and dropped them from 4 feet onto concrete. The magazines never jammed. With regular maintenance they’ll last a lifetime. Magazine bodies followers butt-plates and feeding springs are manufactured by Thermold in the U.S.A. Non-corrosive and self-lubricating; will not jam under normal conditions
