Riflegear Nickel Boron Bolt Carrier Groups, utilizing UCT’s EXO Technology.
The nickel boron that is applied to the bolt carrier group is not merely a coating, it bonds with the metal at the molecular level so it will never chip, flake, rub away or build up carbon. The coating is permanent and is intended to last the entire lifespan of the treated parts.
The main advantages of the coating is it creates a permanently lubricated surface reducing the friction, eliminating the need for excessive lubrication, and creates a surface that is harder than the bolt carrier group tool steel it is enveloping. We at Riflegear do not recommend running any weapon ‘dry’, but the obvious advantages of an oiled nickel boron BCG versus an oiled regular phosphate finished BCG would be more rounds between lubrication cycles.
Ultimately, nickel boron coating on the bolt carrier group is an advantage because of reduced friction thus treated parts run significantly longer with less heat and maintenance. When you need that few extra hundred rounds before your gun fails due to the lack of lubrication, Nickel Boron is for you.
