This trigger works great. its a little tricky at first because you have to find the point in which you get the maximum bps. Once that point is found it is very consistant. Its easy to install and is well protected by that hard Tippmann frame. I believe it is ment for a double trigger but even with a single trigger it works good. Thats all i used. When I was playing for an extended period of time the response froze up (this was in about 45 degree weather with CO2). The gun works but works as if you didnt have a response trigger. Just get air and you will be fine or stick to playing in warm summer days. With air it is recommended that you get low pressure kit and a secondary regulator. its pricy but do it. The gun is a high pressure gun and using this kit makes it shoot more consistant and evenly. Do not set pressure at anything lower than 400. 450 to 500 is the best pressure to be at.
Its great and its worth it. Replace o-ring on it once a year or two and you are good to go. Its a Tippmann product which is normally reliable.
