18" 450 BUSHMASTER Stainless Bull Barrel AR15 Upper Receiver with 15" Rail and Multi Port Compensator

The straight walled cartridge of the 450 Bushmaster is ideal for big game hunting, especially in states that restrict tapered cartridges. Shooting a projectile upwards of 250 grains, 450 Bushmaster is a favorite among deer hunters in the Midwest. The .450 Bushmaster is designed to be used in standard AR15s. We recommend single stack magazines for reliability and our bolts are specially designed to eliminate feeding issues.
