The Ares Armor Effin-A Comp and its innovative tuning feature are now available in a more refined MKII version. The Ares Armor Effin-A Compensator 5.56 MKII retains much of what was great about the original but reduces the weight by half and adds some notable functionality.
The new version of the Effin-A features 7 rows of 3 ports. Like the original, the ports can be opened or closed by inserting provided set screws. The new MKII version adds limiters so that the set screws bottom out. This allows them to stay tight even when being buffeted by muzzle blast and prevents the user from accidentally tightening a screw so it sticks down too far into the muzzle device.
The MKII version has had a lot of its excess material machined away. The result is that the MKII weighs just 2.5 ounces or half of what the original weighed. That is impressive.
