Nicknamed the "thumper," the .450 Bushmaster round pushes a 250-grain projectile at 2,200 FPS. With 2,800 foot-pounds of muzzle energy, it delivers plenty of knockdown power for everything from feral hogs to bear and elk. Now's your chance to start an AR build chambered in the potent round.

The 450 Carbine Complete Upper is well-made, features nice fit and finish, and comes with a BCG and charging handle.
