My new Ballistic Advantage 20" DMR fluted barrel

The same as any AR15 with the same gas port length.
Do you think the BCG will hold back all the pressure?
Besides, this is a rifle length port which is 13" from the breech.
It is more similar to a ported barrel than you think. Even better than the group buy 12.7" barrels.
In fact I notice an EXTREME REDUCTION in muzzle rise when I shoot it uncovered.Cool
