What Is Titanium Nitride (TiN): It is a coating that is wear resistant, inert and reduces friction substantially. This finish is used on CNC cutting tools and dies to enhance the life of tools & aerospace components. Now used in the firearm industry to improve Bolt Carrier Group life two to ten times, or more, over oxide or phosphate Bolt Carrier Groups. This amazing finish is comparable to DLC wear resistant wise but has additional self-lubricating qualities that make it superior to most DLC finishes. Previously the cost of the titanium nitride finish made it very expensive to do on bolt carrier groups but in the past few years, it has dropped significantly so that now it's an affordable option where at one time it would cost 3-4 times what a premium finished BCG would cost. Making this Bolt Group now one that is definitely worth buying where its less than even some of the premium phosphate finished Bolt Carrier Groups.
