*BARRELS & BOLTS MUST BE PROPERLY CHECKED FOR HEADSPACE PRIOR TO USE. FAILURE TO DO SO MAY RESULT IN FIREARM DAMAGE, PERSONAL INJURY, OR DEATH*

Disclosure: Chrome-lined barrels are finished chambered and cannot be altered. They may not be compatible with all rifle receivers and/or bolt combinations. While most rifles are designed to accommodate chrome-lined barrels, some receivers/bolts may have tolerance allowances that can prevent the barrel from being properly headspaced. It's important to carefully consider the compatibility of a chrome-lined barrel with your rifle receiver before making a purchase. If you're unsure whether a particular barrel or bolt will fit your rifle, contact us for information about our headspace verification services. It is the only way we can guarantee your completed rifle is within specs and safe to fire.
