U.S.A.-(Ammoland.com)- .450 Bushmaster has risen in popularity, especially in states with straight-wall cartridge hunting restrictions. DURAMAG has solved the geometry and durability problems of putting straight-walled, big-bore rounds in a magazine designed for smaller, tapered cartridges by simply not doing it. Unlike other stop-gap solutions such as after-market followers or springs, the new DURAMAG .450 Bushmaster is a complete solution designed from the ground up to properly support the round in a magazine that fits into the AR15 magazine well.

Until now the challenge has always been the magazine. While originally intended to fit a standard AR15 magazine, improper geometry and follower design has led to feeding issues and rifle malfunctions. Some home-remedies worked, but the unique stresses caused by this load typically deformed the magazine after just 10-20 cycles.

Thousands of rounds from a single magazine of in-house and third-party testing by firearms manufacturers have confirmed DURAMAG is the answer. An advancement in magazine design and construction has made this possible. By creating a proprietary internal bracing system and laser-welding it into a 410 stainless-steel body, DURAMAG is able to control round stack and prevent misalignment when rounds attempt to double stack. DURAMAG's system also ensures the thousandth round feeds just as reliably as the first. This .450 Bushmaster-unique development is in addition to the suite of technology DURAMAG fans have come to rely upon:

  • LipLock technology keeps rounds secured and in proper alignment.
  • Advanced Geometry Follower remains level for consistent feeding.
  • T-360 total coating technology covers the entire magazine, inside and out.
  • EverFlex anti-fatigue spring technology for long life and ultimate reliability.

Very glad to see someone finally made a magazine with feedlips designed for .450B instead of just changing the follower.

About time. It is well known that no mag made for standard rounds can ever function properly for a rebated rim round. Rebated rim rounds have special needs to feed through a box magazine area, since their smaller than body diameter rims require special support to feed properly from a box mag. Standard tube magazines are likely fine, but not many are going to want a .450 Bushmaster in a lever action.
