Description

SV Precision Black is the hardest, most wear resistant and smoothest bolt carrier group coating available. Created from a highly advance Chemical Vapor Deposition (CVD) technology that produces a flexible pure form of amorphous carbon, consisting of sp3 bonded carbon atoms. Having the surface characteristic of both lipophilic and hydrophobic makes it non wettable with water but easily wet with oil; a characteristic found in few bolt carrier group coatings. This technology produces excellent tribological properties that make it very suitable in environments with extreme contact pressure and sliding actions. When you choose Black, you are choosing the lowest coefficient of friction coating on the market today requiring minimal to no lubrication. In addition, Black is a chemically inert coating that reduces carbon build-up. This top-of-the-line bolt carrier group coating will enhance performance and precision due to a much smoother sliding action while also displaying a sleek external appearance.

Properties:

  • Coefficient of Friction: 0.01
  • Hardness: 3000 Vickers
  • Max Temperature: 1,100° F
  • Thickness: 2-3 microns
  • Color: High Luster Black

Advantages:

  • Increased Lubricity
  • Wear Resistant
  • Smoother Recoil
  • Improved Consistency
  • Faster Cyclic Rate
  • Easier Cleaning
  • Reduced Carbon Fouling
