I installed it immediately but didn't have much of chance to test it out until yesterday. So when its not cocked, the two stages are noticeable my touch and sight. First stage is about 3/4 of the pull then the 2nd stage for the last quarter. Once the gun is cocked however, I barely touch the trigger and it will fire. I'm talking like maybe 5mm to 10mm of pull at most. I've taken it apart on reassembled it 3 times according to the PDF from the site for the GTXII trigger. I've attempted to adjust it as well with no success. Can I get some thoughts on the issue? This is my first mod I've done myself to a rifle, but I followed the instructions through to my knowledge. _________________ Crosman Phantom 500 IndustryBrand QB78 Beeman P17 Umarex Steel Storm   Posted: Tue Jun 28, 2011 12:34 pm SMP Silver Status Member Joined: 04 Feb 2011 Posts: 1183 Location: Just south of "Out There"- Land O Lakes Ontario There are two screws on the GTX one sets the sear and one sets the travel. You probably need to back off the travel screw(this is the one they they tell you does not need to be adjusted in the PDF) http://www.airgunsofarizona.com/GTX/GTXadjust.pdf Back off the secondary 1/2 of a turn then try to adjust the primary. And the feel when the gun is uncocked actually is not the same as when it is cocked _________________ Sean   Posted: Tue Jun 28, 2011 12:38 pm bloodwulf New Member Joined: 10 Jun 2011 Posts: 5 Location: Halifax So a half turn CCW? I'll give that a try after work and get back to you _________________ Crosman Phantom 500 IndustryBrand QB78 Beeman P17 Umarex Steel Storm   Posted: Tue Jun 28, 2011 12:48 pm SMP Silver Status Member Joined: 04 Feb 2011 Posts: 1183 Location: Just south of "Out There"- Land O Lakes Ontario Yes 1/2 a turn CCW on the secondary Then tune the primary. If it is still on the knife edge back it out (primary)CCW until you can feel the distinct 1st and second stage when the gun is cocked Test the trigger between adjustments under normal shooting conditions( cocked, loaded and fired safely downrange) And properly adjusted the pull can be very short. 1-2mm first stage and then a crisp break at the 2nd stage resistance _________________ Sean   Posted: Tue Jun 28, 2011 12:56 pm bloodwulf New Member Joined: 10 Jun 2011 Posts: 5 Location: Halifax Thanks for the tips, I'll give them a try and get back to you.

I had to adjust the GTX II I put in my Quest too. As recieved, it was about the same as the stock trigger - no second stage and plenty creep. A minute or so of adjustment had it set in the zone where it has sat now for 1000 shots or so. _________________ Duke ))))----//----------==   Posted: Tue Jun 28, 2011 11:08 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6929 Location: "Out There" "Back out screw kind of guy" - I'm not sure how I should take that- it's just unclear enough the permutations of it seem pretty extensive... _________________ ` I'd say "I care."
