SV Precision Bronze is a Physical Vapor Deposition (PVD) bolt carrier group coating having all of the same desirable properties as SV Precision Gold but with better wear and lubricity characteristics. In fact SV Precision Bronze has the highest lubricity of all the ceramic based coatings – making it an excellent choice as a dry film lubricant where improved wear resistance and reduced friction are desired. As with all the SV Precision bolt carrier group coatings; peak cyclic rate and consistency due to increased lubricity and smoother action under high-load conditions can be realized. It’s all about the creation of a smoother stable platform.
