Critical trigger on DM4, used a teammates Ion w/ Critical trigger. Used stock trigger on all 3 guns previous to the Criticals.
06 dust purple Ego, gloss purple Nexus CCM kit, Critical Trigger, Dye UL barrel, Pure Energy 68/4500, HaloB w/ Rip and Cheetah board.
Fast, comfortable, reliable
Price(though it is worth every penny)
Again, Critical Paintball doesn't disappoint. Though the installation is a little bit on the difficult side, the time and cost of the trigger is well worth it. It's fast, comfortable, and doesn't bounce with a Debounce of 5 on the stock board, and only occasionally bounces on 3 for my gun.
I recommend this for anyone who can afford it, and advise anyone who can't to find a way to be able to. I am very satisfied with my trigger; IMHO, this is the best trigger out there. Anyone who hasn't tried one yet, you should.
