TRIARC Systems NP3 Coated Mil-Spec Bolt Carrier Group, AR-15

****Coating Notes*****

NP3 is a surface treatment for various metals and alloys that combines sub-micron particles of PTFE (Polytetrafluoroethylene) with autocatalytically applied nickel/phosphorus. The result is an accurately applied, dry lubricated, low friction surface that is extremely hard and resistant to wear. When cleaning is required, the effort needed is minimal – usually requiring only a soft cloth. NP3® is very corrosion-resistant.

• • Increases reliability.

• • It requires little to no oil for lubrication, although we recommend using some oil during break-in.

• • Accurate and even coatings on all activated surfaces.

• • Permits firing for extended periods between cleaning, as dirt and powder residue has no wet or oily surface to cling to.

• • NP3® has a microhardness of 48-51 Rockwell as plated (nickel matrix).

• • NP3® is very corrosion resistant, with a 1 mil (.001) coating exceeding a 250-hour salt spray test.

• • NP3® has high lubricity and low friction coefficient; therefore, the life expectancy of a firearm will be greatly increased due to reduced friction wear.

• • The coating is strippable with no effect on the base metal, allowing other coatings or a new coating of NP3® to be applied, if necessary.

• • NP3® plated onto stainless steel guns will prevent galling, a problem common with stainless steel.

• • NP3® is a satin gray, non-reflective color ideal for all firearms.

• • NP3® can be plated to all internal parts giving a smoothness to the action not found with any other coating.

• • In cases where the NP3® has been perforated, the corrosion shows no tendency to spread or migrate under the coating.

• • NP3® is guaranteed against corrosion, peeling, or flaking for the lifetime of the firearm.
