View Full Version : AR question regarding barrels

To properly measure a AR barrel, do I do it from end to end considering the tread as part of the barrel or not?

I appreciate any info on this, thank you all.

Bolt face (not the end of the barrel extension) to the end on the barrel threads or the end of a permanently attached muzzle device.
