Colors & Finishes

Fiberglass stocks for the tactical series are available in the three colors shown below. Most exterior metal surfaces receive a matching Cerakote coating. This provides additional corrosion resistance for harsh environments and gives an excellent base coat for tactical marksmen who will later paint their firearms to match the urban or field conditions where they are deployed.
