Built to harness the ballistics of the .450 “Beast Of A Round” (BOAR), the latest Bushmaster offering is tricked out for the hunt. Incorporating high-quality aftermarket parts from companies like Magpul, the rifle offers a high-end experience shooters will appreciate. Likewise, a two-stage trigger upgrade promotes enhanced accuracy from the .450 Bushmaster BOAR round.
The Bushmaster .450 Bushmaster BOAR
The BOAR is built on a 7075 forged XM15-E2S lower coupled with a 7075 forged modified A4 flat top upper. Featuring a salt bath nitride finish, the rifle is ready for any conditions your big game hunt may take you. Similarly, the salt bath nitride bolt carrier group and MPI-tested bolt also provide durability and reliability in any environment.
Providing the interface to the rifle is a Magpul UBR collapsible stock and Magpul MOE grip. Housed within the buffer tube is a heavy buffer spring that significantly reduces the felt recoil of the .450 BOAR. Likewise, the grip also works to add another level of comfort and control.

Chambered in .450 Bushmaster, the 20-inch 4150 CMV barrel with a 1:24 twist rate also features a slat bath nitride finish and carbine length gas system. The barrel includes a 1/2×28 thread pitch for attaching a suppressor or other muzzle device. However, the rifle comes with the Bushmaster Snake Charmer muzzle brake for improved muzzle control.
A 14-inch BFI M-Lok handguard includes M-Lok slots around the circumference of the guard, with the exception of the top. The top of the guard has a full-length Picatinny rail that joins with the rail on the A4 upper. As a result, you can add any accessories, such as lights, optics, etc., in any configuration that works for you.
Housed within the Magpul MOE Enhanced Trigger Guard is the DM2S 2-stage trigger. Bushmaster’s Dedicated Marksman 2-stage trigger features a 4.12-4.46-pound unlubricated pull weight and a 3.12-3.71-pound lubricated pull weight. As a result, the trigger helps promote the kind of accuracy necessary for a long-range big game hunt.
