MVB Industries AR-15 45ACP Maxwell Adaptor
MVB Industries AR-15 45ACP Magwell Adaptor
MVB Industries AR-15 45ACP Magwell Adaptor is designed as a drop-in accessory for a standard AR-15 lower receiver and uses a standard H&K USC 45 caliber magazine.
It Will not work with the New Frontier Armory .45ACP bolt, as it has a geometry that makes it incompatible with the feed angle of H&K USC pattern magazines. Visit MVB Industries
