Why we made BUSHMASTER® 450 Bushmaster 20"

Introducing our 450 Bushmaster rifle, the ultimate hunting companion for big game throughout North America. This rifle is the perfect choice for hunters looking for a powerful and reliable firearm that delivers a satisfying experience in the field.

One of the standout features of our rifle is its ability to significantly reduce felt recoil. This makes it a pleasure to shoot, even for extended periods. The 450 Bushmaster cartridge provides the stopping power needed to take down large game, ensuring that you'll never miss your shot.

Our rifle is built to last, with a 20" barrel made from 4150 CMV steel and finished with salt bath nitride for added durability. The barrel features an 11/16 x 24 thread pitch and a twist rate of 1:24, ensuring accuracy and consistency with each shot.

The rifle is equipped with a carbine-length gas system, a 7075 forged XM15-E2S™ lower receiver, and a 7075 forged modified A4 flat top upper receiver. The bolt carrier group has also been treated with salt bath nitride, and the bolt has been MPI tested for added peace of mind.

Other features include a 14” BFI® M-LOK handguard, an A2 fixed stock, an A2 pistol grip, a DM2S® 2 stage trigger, and a Snake Charmer™ muzzle brake. The rifle also comes with a 5RD aluminum BFI® 450 magazine.

We're proud to say that our 450 Bushmaster rifle is made in the U.S.A., and we stand behind its quality and performance. Whether you're an experienced hunter or just getting started, this rifle is sure to impress.
