AR Bolt Carriers interchangeable with different uppers? Is it okay to use the same bolt carrier group on a new barrel?
Matthew Answered question July 5, 2022
No, bolt carrier groups are not interchangeable. Each one is specifically designed for a particular make and model of firearm. In most cases, even different models of the same make and caliber of weapon will require different bolt carrier groups. Attempting to use an incompatible bolt carrier group can cause serious damage to your firearm and may even render it inoperable. So, if you’re unsure which bolt carrier group is right for your gun, always check with the manufacturer or a qualified gunsmith before making any changes.
