The world’s first tunable .308 compensator. Featuring a black nitride finish and 24 gas ports, the .308 EFFIN-A AR-10 Compensator is designed to allow users the ability to adjust the manner in which the gas exits from the weapon. This .308 compensator features 8 columns and 3 rows of exit ports that can be either opened or closed through the very simple use of set screws. The exit ports are not threaded completely through to eliminate the possibility of the screw being over turned into the chamber. This feature also allows the screw to “bottom out” increasing tightness and ensuring that it will not work itself out under the pressure of the gasses being released by the weapon. This EFFIN-A .308 AR-10 Compensator weighs in at only 2.5 ounces; which is half the weight of the previous version. Allen Key is included.
