Detailed Description

Manufactured by the finest Mil-Spec contractor, these are the best AR rifle bolts we have found.  This is the same bolt carrier group found inside every Wilson Combat Custom Rifle.

Completely NP-3 plated, the semi-auto carrier includes the proper Mil-Spec gas key that is chrome lined and heat treated per GI specifications. The gas key is secured to the carrier via USGI domestic mfg Grade 8 fasteners and properly staked per Mil-Specs.  These properly hardened parts ensure proper gas system functioning.

The bolt assembly is machined from the correct Mil-Spec Carpenter No. 158® steel, shot peened for increased strength and a includes tool steel machined extractor and ejector, appropriate extractor spring, and is HPT (High Pressure Tested) and MPI (Magnetic Particle Inspected).

What is NP3?

NP3 is a surface treatment for steel and metal alloys that combines sub-micron particles of PTFE (polytetrafluoroethylene), otherwise known as Teflon, with electroless nickel.


  • Very accurate and even coatings on all activated surfaces.
  • No lubrication is needed on opposing surfaces.
  • Cleaning is minimal, usually requiring only a soft cloth.
  • Permits firing for longer periods of time between cleaning, as dirt and powder residue has no wet or oily surface to cling to.
  • NP3 has a micro hardness of 48-51 Rockwell as plated (nickel matrix).
  • NP3 is very corrosion resistant, a 1 mil (.001) coating exceeding a 240 hour salt spray test.
  • NP3 has a high lubricity and low friction co-efficient; 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.


What's the difference between a mil-spec full-auto carrier and a semi-auto carrier?

I love the NP3 coating on the BCG. Very easy to clean and always has a smooth slick feel to it. Never had any problems.

Wilson Bolt Carrier 4/13/2011
I have been running this BCG for over a year in my WC 18 Recon. I have put a LOT of hot rounds through it and it still runs extremely smooth and the finish is still 100% intact. Highly recommended. Charles Coker www.TacticalGunReview.com

What a wonderful BCG. Like butter in my RRA 6.8 SPC carbine rifle. No malfunctions, No FTF or FTE.
