Armtac now has the Ares Armor Effin-A Tunable Compensator ready for pre-order. For either the 5.56 or 7.62 version this comp will set you back $115 + S&H. Here is the info that Armtac has supplied about the comp.

The EFFIN-A Compensator was designed to allow the end user the ability to adjust the manner in which the gas exits from the weapon. The EFFIN-A features 7 columns and 4 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 Compensator also features the ability to “Stack” multiple comps end to end giving further options to the end user.
