nickel boron nitride is a durable metal finish that offers superior wear resistance and low friction. This is one of the most technologically advanced composite plating processes available and it has applications in the aerospace, defense, medical, telecommunications and industrial industries.

The Benefits of a Nickel Boron BCG

When the surfaces of your bolt carrier group (cam pin, upper receiver, carrier and bolt) are properly lubricated with a self-lubricating coating it is far less likely that you will experience any failures or wear related to feeds, extractions or ejections of rounds. This is especially important with suppressed AR pistols or shortened gas systems in AR15s.

This is why some of the best barrel manufacturers in the world use Nickel Boron plated barrel extensions on their highest end products. These include Ballistic Advantage and Toolcraft.

A Nickel Boron BN BCG is so durable that it is even specified on Army 81mm mortar tubes, Blackhawk helicopter hoists and for hard use applications on some Navy ships!

BN is also an eco-friendly alternative to hexavalent chromium. It has an excellent hardness, is extremely resistant to abrasion and is able to be formed into a cubic (sphalerite structure) type that has superior thermal and chemical stability.

The process of electroless nickel boron nitride is similar to that of nickel phosphorus plating except that the nickel salts are substituted with boron-containing reducing agents, such as alkylamineborane or sodium borohydride. The coating is deposited from a solution containing the boron-containing reducing agent, nickel ions, a buffer, complexant, and control chemicals.
