Great Lakes GLFA AR-15 450BM 18in | .450 Bushmaster

The Great Lakes GLFA AR-15 in .450 Bushmaster is a modern sporting rifle built around a heavy .450 chamber and an 18-inch stainless barrel finished in Pursuit Green Cerakote. It combines a 7075 billet upper and lower with M-LOK modularity and a 15-inch aluminum handguard to provide a rigid, accessory-ready platform. For optics, a rugged variable such as the Vortex Crossfire II 2-7×32 pairs well with this rifle and remains well under $1,000. Typical applications include short- to medium-range big-game hunting and brush-country hunting.
