This is a factory-made Ruger magazine built from the ground up for the American Rifle chambered in .450 Bushmaster. It's a straightforward, no-frills magazine designed to feed reliably in the short-action magazine well of compatible American Rifle stocks.
The magazine is molded from durable polymer in a black matte finish, keeping weight down without sacrificing toughness. Inside, you get a steel wire spring paired with a polymer follower for consistent feeding. The pivoting locking lug makes both removal and secure lockup in the rifle straightforward, while embedded panels at the bottom give you a solid grip for quick mag changes out of the stock.
With a 3-round capacity, this magazine is built for the realities of hunting and range work with the .450 Bushmaster. The cartridge is hefty, which is why the magazine sits slightly proud from the stock when loaded, but that stubby profile actually makes it easier to grab. What matters most is that the feeding works cleanly and the construction holds up. Owners report these perform well in training, hunting, and competition settings, with fit and finish matching the original magazines that come from the factory.
Ruger magazines are engineered to Ruger's own specifications, which means they're built with the same tolerances and quality control as the originals. If you're after a reliable spare or replacement magazine for your American Rifle in .450 Bushmaster, the factory OEM magazine is the safest choice. The .450 cartridge puts unique stresses on magazines that other platforms don't, so sticking with Ruger's design just makes sense.
No. This magazine is designed specifically for the Ruger American Rifle chambered in .450 Bushmaster. The American Rifle is offered in multiple calibers, and each requires its own magazine pattern. Always verify your rifle's caliber before ordering a replacement magazine.
The .450 Bushmaster is a large-diameter cartridge, so the magazine protrudes slightly from the underside of the stock when seated. This is normal and by design. The molded grooves at the bottom give you a solid grip point for quick removal, which actually makes it easier to handle than a flush-fit magazine would be.
Yes. This is a factory OEM Ruger magazine engineered to the same specifications and tolerances as the magazines that ship with new American Rifles. It's built for training, competing, and hunting. Users report consistent feeding and durability with proper care.
This is a modern detachable single-feed magazine, while some American Rifles ship with a rotary magazine. The detachable design is simpler, faster to reload, and many users find it more reliable. Some owners have switched from rotary mags to this style for those reasons.
