The SV Precision Titanium Nitride BCG 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. 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 and service life.
