Description

BLEMISHED ITEM - MAY HAVE COATING INCONSISTENCIES, SCRATCHES, WEAR MARKS, MIS-LASERED LOGO, NO LOGO OR OTHER BLEMISH WHICH WILL NOT EFFECT THE FUNCTIONALITY OF THE ITEM.

A smooth nickel boron (NiB) 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 AR-15 or M16 platform .223 / 5.56 or 300 Blackout pistol or rifle and is completely legal in all 50 states.
