Great Lakes GLFA AR-15 450BM | 18in SS | 5rd

The Great Lakes GLFA AR-15 450BM is an AR-style rifle chambered in .450 Bushmaster with an 18-inch barrel and OD Green Cerakote finish. It ships with a single 5-round Lancer magazine, mil-spec controls, and a 6-position collapsible stock for adaptable handling. The rifle is set up for larger-bore, short-range performance and is aimed at shooters who need dependable function in brush and big-game field work.
