TRIARC Systems AR15 5.56 / .300 BLK Enhanced Bolt Assembly – NP3 Coated

****Coating Notes*****

NP3® metal finish offers many benefits. NP3® permits firing for longer periods between cleaning, dirt, and powder residue have no wet or oily surface to cling to. When cleaning is required, the effort needed is minimal – usually requiring only a soft cloth. NP3® is very corrosion-resistant. It provides a high lubricity and low friction coefficient, greatly increasing the life expectancy of a firearm due to reduced friction wear. NP3® is a satin gray, non-reflective color ideal for all firearms.

• • Increases reliability
  • It requires little to no oil for lubrication, although we recommend using some oil during break-in.
  • Very accurate and even coatings on all activated surfaces.
  • Permits firing for longer 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 to be applied 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.
