WMD AR-15 NIB-X Semi Auto Nickel Boron BCG Bolt Carrier Group Polished

WMD NiB-X AR-15 Semi Auto Bolt Carrier Group Polished

Are you looking for a top-quality bolt carrier group that will provide reliable performance and easy maintenance? Then look no further than the WMD AR-15 NIB-X Semi Auto Nickel Boron BCG Bolt Carrier Group. Because this BCG has been designed and manufactured by Military defense vendors to meet WMD’s tight tolerance specifications, that makes it one of the best BCGs on the market. The NiB-X nickel boron coating provides excellent durability and corrosion resistance, while also making cleaning and maintenance a breeze. Since, all of the components of the bolt carrier group have been coated with NiB-x, they have been polished to a mirror finish. So, if you’re looking for a high-quality, easy-to-maintain BCG, the WMD AR-15 NIB-X Semi Auto Nickel Boron BCG is the perfect choice for you.

NIB-X is WMD Guns’ proprietary nickel boron coating process applied directly to the bolt carrier group components. Nickel boron is an electroless coating that bonds at the molecular level to the steel substrate, producing an extremely hard, slick surface that dramatically reduces friction between the bolt carrier and the interior of the upper receiver. The reduced friction translates to smoother cycling, easier extraction, and a BCG that is significantly easier to clean than phosphate or parkerized carrier groups — carbon fouling wipes off the slick surface rather than bonding to it as it does with matte finishes. The semi-auto carrier profile features a modified tail section compared to the full-auto/military carrier profile. Semi-auto profile carriers are designed specifically for semi-automatic AR-15 lower receivers and are the standard configuration for civilian AR-15 builds. The bolt is machined from Carpenter 158 steel and magnetic particle inspected to mil-spec standards. The carrier is machined from 8620 steel and heat treated for durability. All components meet or exceed mil-spec dimensions for compatibility with standard AR-15 upper receivers, barrels, and gas systems. The polished NIB-X finish provides a bright silver appearance and maximum surface slickness for easy cleaning and smooth operation.
