The AR-Stoner Enhanced Bolt Carrier Assembly features a fully staked gas key. The carrier body has a relief cut at the rear to allow for the installation of a carrier weight system (like the Tubb CWS). This cut eliminates the need to remove both takedown pins to slide the recievers together, the gun pivots on the front pin as normal.





Technical Information:



Available with two different coatings:



Nickel Boron: Microscopic "Nano Domes" formed at the surface provide dry lubricity and affords hundreds of hours of salt water protection. Nickel Boron coating is easy to clean and resists fouling.



Ceramic: Excellent heat resistance and provides for rapid cooling. Applied through a proprietary process that penetrates the substrate of the metal and CAN NOT be removed without removing a layer of the metal itself. The hotter it gets the slicker it gets-continues to resist fouling even during extended firing sessions.



*Note: Color pigment loss will occur within 3-5000 rounds, this is NOT a loss of ceramic material, simply a loss of color.
