This is what 2A Armament says :



The T4 is based on the great performance and design as the T3 compensator only in an ion bond black finish, and without the serrated end (which makes it very scabbard friendly).  This dual baffle compensator directs expelled gasses to control muzzle direction. The initial baffle directs gas in a geometrical pattern that stabilizes the rifle system. The second baffle system channels gasses upward to compensate for muzzle rise. This gives the shooter the ability to decrease time between follow up shots and maintain control of muzzle direction. The T4 Titanium is made from 6AL-4V Titanium, and is a lightweight mounting solution for suppressors that mount via an A2 style flash hider.
