The Great Lakes AR-15 redefines what a budget-friendly MSR can be, boasting precision-machined components made right here in the USA for a price that puts the competition to shame. Starting with forged aluminum receivers, the flat-top upper is matched perfectly to the free-float M-LOK handguard for a seamless picatinny top rail that runs the full length of the rifle. It comes with a premium 416 stainless steel barrel that's threaded and comes with a GLFA muzzle brake to keep you on-target. - CALIBER .450 BUSHMASTER - MAGAZINE (1) 5rd capacity
