F&S Engraving works with supply manufacturers that provide stamps and dies used by the firearm industry. All firearms are stamped with serial numbers for federal and state registration. They are stamped with sharp-faced dies to mark model number, gauge, and manufacturer name and location. Sharp-faced stamps create micro fissures, which still allow guns to be identified when the number is filed down. Sharp-faced roll dies are also used by rifle manufacturers for creating checkering and other designs on guns stocks. Roll marking dies are used for marking range and distance calibrations for rifle scopes and other components, such as silencers used within the firearm industry.
