SV Precision Gold is a hard, wear resistant Physical Vapor Deposition (PVD) bolt carrier group coating that provides good dry film lubrication. Its lustrous golden color adds a superior external touch that distinguishes itself above other coatings. However, this bolt carrier group coating is more than its external superiority – it also will assist in increased speed and consistency performance through its low coefficient of friction similar to its sister coating, SV Precision Bronze. With the reduction of friction of any sliding action a calmer more stable platform is created. It’s this platform stability that provides an environment for improved performance.


  • Coefficient of Friction: 0.45
  • Hardness: 2600 Vickers
  • Max Temperature: 900° F
  • Thickness: 2-3 microns
  • Color: High Luster Gold


  • Lubricity
  • Wear Resistant
