Product Description:

Surface Coating Reduces Friction, Requires Minimal Lubrication

Drop-in-ready bolt-and-carrier group has a proprietary low-friction coating that minimizes the need for lubricants that can attract and hold grit, bind, or thicken up. BlacknitridePlusSM processing gives the metal a harder, stronger surface than the substrate underneath, providing extreme durability, reliability, and resistance to wear and corrosion, in addition to extending the life of critical parts. Also helps dissipate heat efficiently, so operating parts run cleaner and cooler. Less carbon buildup makes field cleaning easier - fouling wipes away with a clean cloth. Endurance tested for thousands of rounds and magnetic particle inspected to ensure no hidden defects.
