GLFA AR-15 Rifle .450 Bushmaster 18″ Barrel Olive Drab Green Cerakote Stainless Steel or Nitride 5-Round

The GLFA AR-15 Rifle chambered in .450 Bushmaster is a powerful straight-wall cartridge rifle engineered for hunters and shooters who demand maximum stopping power from a modern AR platform. Featuring an 18-inch barrel with a 1:24 twist rate and a rugged Olive Drab Green Cerakote finish, this rifle is built for durability, reliability, and field-ready performance.

Constructed using strong 7075 aluminum receivers, this rifle offers a solid, balanced feel while standing up to hard use. The mid-length gas system promotes smooth, consistent cycling, and the full-length aluminum Picatinny handguard provides ample space for optics and accessories. A factory-installed muzzle brake helps mitigate recoil, making the .450 Bushmaster cartridge more manageable during extended range sessions or hunting scenarios.
