AR-Stoner Enhanced Bolt Assembly AR-15 223 Remington Nickel Boron Plated
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.
