Not too difficult to install.
Much, much, faster rate of fire.
3 inch long straw down the side of your marker.
I bought this product hoping that it would let me compete with my friends Spyder Pilot. I got it for 60ish dollars off of Actionvillage via Amazon.com. i opened up my Tippy a few days before to familiarize myself with the internal workings of my marker. I polished the internals using fine grit sandpaper, oiled it up and put it back together.
I installed the response trigger the day i recieved it. It took me like 20 min to install the new powertube and get everything in the right place. the hadest part was putting the 2 halves back together again. it seems that the new spring but alot more stress on the some of the pins making me have to snap the two halves together. It wa already night when i started installing it so i would have to test it out the next day.
The following morning i took it outside and began to test my new upgrade out. at first i couldn't see anything different, so i began to tinker with the rate of fire screw. It turned out pretty good i was getting really fast rates of fire from a tippmann! It all seemed good.
Later that week i took it out to the paintball feilds.
This is when the problem started.
I would be int the middle of spraying some guy with fire and the gun would just stop firing. I would pull the trigger and nothing would happen. It turned out that the gun was not re-cocking itslef all the way. it would get stuck halfway. id have to re-cock it after about 5 seconds of automatic firing. I am still unable to resolve this problem.
I have not been able to find other people that have had this problem. So it maybe that i overpolished the internals? i dunno.
Pretty good except for the problem i am having. In retrospect, i would probably still buy it. Hopefully i will find a way to resolve this problem.
Same thing happened with me. I bought mine brand new from RockStarSports.com around March '06. When the gun started the "stop firing" problem, i.e., getting stuck un-cocked, it was driving me NUTS. Friend of mine and I took it apart, and the hammer and sear was worn. I called Tippmann, and they told me that they let a bad batch of sear springs get out into the marketplace. They sent me a new hammer, sear, and sear spring. Fixed the problem. No problems since. Give 'em a call. They're great to work with.
