Like new Ruger made AR chambered in 450 Bushmaster. Feels like shooting 20ga slugs at semi auto. Originally bought for hunting in Michigan (if you know the straight wall cartridge law pf the Midwest) brought with for bear hunting. Not been used much at all so time to go. Comes with multiple mags, some ammo and a custom Leupold scope and mount. Scope was calibrated for the 450 bushmaster round specifically.
