DealThese Dead-Bolt +P Gen II Premium Chrome Lined Bolt Carrier Groups have slight (very small) blemishes in their phosphate finish. They are otherwise completely functional and in new, un-used condition. A phosphate finish and chrome lining to military specifications increases durability, strength and service life while reducing clean up time and the amount of dust and grime grabbing oil needed to keep your rifle or pistol running at peak performance time after time for years to come. This second generation features a more robust design which better balances the overall weight and durability while greatly reducing surface to surface friction allowing your weapon to run smoother and cooler. This complete bolt carrier group is a perfect upgrade for any AR15 or M16 platform .223 / 5.56 or 300 Blackout pistol or rifle and is completely legal in all 50 states. from Ground Zero Precision |
