Barrels

100% In House Barrel Manufacturing

A precision Diamondback Barrel begins with a straight bar of cylindrical steel. 

All barrels are turned on center of bore to ensure concentricity to less than .002" 

All barrels are inspected using an air gauge and borescope to ensure they are absolutely free of defects.  This ensures the chamber and bore meet SAAMI specifications and tolerances.

 

All NFA Regulations apply. Please check your local and state laws before ordering. Contact your local ATF Field Office with any NFA questions you may have.
