Over 30 years of plating expertise goes into every Teikuro chrome plated barrel. Control of the plating process is the hall­mark of a quality plating job and the reason Teikuro uses the phrase “engineered surface treatment.” Teikuro plates barrels to the current AMS2460 standard. Systematic monitoring and evaluation of the various aspects of the gun barrel production insures standards of quality are achieved within our process.  Air gauging with computer interface, bore scopes, and testing per the AMS2460 are all integral parts of our quality management process. Proprietary Teikuro electro-polish process is available when required.
