Magazines for New Bushmaster .450 Caliber... While the new Bushmaster .450 utilizes a standard 20 Round AR Type Magazine Box, the similarity ends there. A blue single stack follower (same as used in high power competition to load extra long bullets single shot) is installed above the anti-tilt type follower to facilitate feeding the large diameter .450 Bushmaster.
