Ares Armor have updated their EFFIN-A compensator (the name always makes me chuckle). They have slimmed it down, knocking off half its weight, by reducing the number of ports, from 28 to 21, and removing the ability to stack multiple EFFIN-As in a row Each of the ports can be blocked with a screw so that the user can tune the compensator for their rifle. It is retailing for $89.99.
