Duramag 7 Round 450 Bushmaster AR-15 Stainless Steel Magazine

Duramag 7 Round .450 Bushmaster AR-15 Stainless Steel Magazine
Better Control Of Round Stack & Prevent Misalignment
While originally intended to fit a standard AR15 magazine, improper geometry and follower design have led to feeding issues and rifle malfunctions. By creating a proprietary internal bracing system and laser-welding it into a 410 stainless-steel body, Duramag .450 Bushmaster is able to control round stack and prevent misalignment when rounds attempt to double stack.
The enhanced system of this AR-15 magazine also ensures the thousandth rounds of feeds just as reliable as the first round.  This .450 Bushmaster-unique development is in addition to the suite of technology DURAMAG fans have come to rely upon.
