As what I mean about swapping tubes, with the commercial tube, springs and buffer weights being the same, the mil-spec is .5" shorter, so the spring is being compressed more, so it would take the higher pressure to push the BCG back far/long enough.
So if I switch to a comm. tube, it will not take the high pressure of 556 to run.
Commercial tubes are a different exterior diameter and material, but are not different in length and have no effect on the gas drive or cycle of operation as a stand alone part. The vltor A5 system is the only exception to this rule.
ETA - IG beat me to it.
