PATRIOT RIFLEWORKS NICKEL BORON BOLT CARRIER GROUP M16/M4 (BCG)

PATRIOT RIFLEWORKS M16/M4 Nickel Boron Bolt Carrier Group

This complete PRW bolt carrier group comes magnetic particle inspected and high pressure tested. The carrier is made from 8620 steel and the bolt from Carpenter C-158 steel. The gas key is properly staked, the extractor spring is upgraded with an O-ring for increased tension, and all surfaces are coated with nickel boron using a 6.5% boron content for a harder surface and higher lubricity as compared to the lesser quality Nib BCGs on the market. Nickel boron is also much easier to clean and can help your firearm run more reliably when heavily fouled or with little lubrication. The Patriot Rifleworks logo is engraved on the right side of the carrier and will show through the ejection port.
