Yes I have and it didn't help
Ok so this gun is awesome! Shot a few mags throu it and its crazy accurate out of the box I finally came off the reg and velocity started to drop then i shot one shot and the valve stuck open and it dumped all the remaining air out. Tried filling it back up but the valve seemse to be stuck open never worked on one of these so wanted to know what i should do first?
I really cant believe how well balanced this rifle is. Its so easy to shoot off hand. The trigger is nice but a little heavy compaired to what I am used to. Tomorrow I might adjust it a little. I had a hatsan Glatian in .25 before this and really liked it but its not even half the gun this is.
