ICS Armalites use a similar (though not the same) adjustment system and it's not compatible with anything but ICS. I'd be interested to see if it's made a well and tightly as the Prometheus HopUp and how it would work with the Shredder spacers. Be nice not to have to adjust your hopup every couple of games.
