DealThe Ares Armor Effin-A Compensator 9mm MKII is designed to allow users the ability to adjust the manner in which the gas exits from the weapon on their 9mm caliber Carbines, AR Pistols, or even a 9mm Pistol with a threaded barrel of the same thread pattern. The Effin-A Compensator MKII 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. Weight of 2.9oz Thread pattern of 1/2x36 Allen key and screws included from Granite Ridge Outfitters (Product EFFIN-A MKII 9mm) |
