[ARCHIVED THREAD] - Barrel diameter

Posted: 5/21/2017 10:02:05 PM EDT

Anyone know off hand the barrel diameter of a BCM 11.5 light weight in front of the gas port? Looking at pics it seems to be just a hair smaller than the .625 gas port, maybe .60, but read sometime back it was like .55 or so...

It's most likely .570".
