It may be a bit before I can tear into it again, my valve rod buffer o ring was chewed up also, just put a new one on when I had it apart, will definitely try the 90. I have a suspicion its an issue in the rear block, the rear pressure gauge appeared to have been bottomed out and the thin web at...

Issues persist: It held air overnight, but it seems to be losing air between shots; I notice if I have a break between shots, reloading, checking targets, or whatever reason, it loses power/velocity, then next shot with no pause in between is right back where it should be. Even in normal...

It held pressure overnight. Any ideas why it would leak initially, and then with no changes other than taking the bottle off and putting it back on, now it doesn't leak? I think I once heard someone at the shop saying they do that some times, but I don't know the cause or the fix.




Well, the pinch groove desperately needed deburred, I actually found the little sliver from the new o ring. I dressed up the edge, put a new o ring on the valve tube, put it back together and when I screwed the bottle on it still leaked from the trigger well area, so I pulled the bottle back...

son of a gun, the second valve tube o ring is cut again, same one I just replaced, and I was super careful with it. guess I'll have to break out the riffle files and dress those edges. Not sure if this is actually the problem but its where I'm gonna start. Thanks Txboy!

Kinda hard to isolate, any issue using some soapy spray?

Down and dirty: I broke it down far enough to remove the rear block to take some measurements for a custom barrel. I put it back together and there was an air leak coming from the trigger well. I used Mr. Rowe's vids to service the valve, only found one damaged o-ring on the valve tube, but...

Anybody make their own barrel for the Impact yet? I'm waiting on a .30 cal. WL blank , it comes 28" so I figured I'd go ahead and make it 28", it can always be cut back. Any suggestions, recommendations, or lessons learned would be greatly appreciated. Thanks

I purchased a new .30 barrel, but it would not completely lockdown in the gun and the air transfer port was cut into the o ring groove. I returned the barrel for a replacement, the machine work was the same as the one I brought back, "that's how they all are". Got it home and locked up good with...

Tominco, Exactly what is "opened all the way up" , with my valve 1 full turn beyond the 4th hash mark my impact will not push a .25 JSB 25.39 past 970 fps. It doesn't shoot well at that speed anyway, but when I do bump up to .30 I may be looking at some anemic numbers. All of my settings are...

After sorting out the pressure/gauge issue then look at other possibilities That L/R POI shift could potentially be the scope, the nice thing about PCPs is no appreciable recoil, so you can put any cheap scope w/ short parallax on it to verify. Check all action and stock screws. I'm not familiar...

yep, airtanksforsale, great white.

Heat up the muzzle end, not so much the shroud tube but the air stripper. The air stripper is threaded onto the end of the barrel with mild thread locker. I used my cigar torch lighter for 15-20 seconds, it doesn't take much heat. I chucked my barrel in the lathe to remove the shroud system but...

I removed the barrel for easier inspection and cleaning, also removed the barrel shroud/stripper assembly. I couldn't see the crud in the barrel with it on the gun. I had only ran a few mags. through it before checking/cleaning the barrel. The smooth bore sector was streaked and the rifled...

I was able to shoot a few mags today. I tested the stripper/muzzle distance at 3/8, 7/16, and 1/2, so far 1/2" produced the best group. Way to early to draw any conclusions, but its already shooting better than the OEM stripper so the preliminary results are encouraging and at least now I know...

Search the web for published shot groups/strings from the .22 Wildcat, lots out there, record the velocities from the different postings, establish a range of velocity, start at the low end and work your way up until you get the best groupings. I would recommend checking closely and cleaning the...

Z, I've had both guns in .25 cal., Impact and Wildcat, for over a month. Having shot both guns a good bit, I believe the Impact is marginally more accurate. Keep in mind there's no love lost between myself and the Impact because I absolutely lost my enthusiasm and excitement for it, so its not a...

ILI, thanks. My first prototype for the .25 has a bore of .277" ( "I" drill ), slightly tighter than OEM, my thought was tighter should be better, to a point, but only experimentation will tell that tale, I can modify or build another stripper insert if it turns out to be too tight. I built...

I doubt the professional reviewers received a "special" gun, but I'd be willing to bet they at least got one that test fired "well" off the rack. Had they received one straight out of the box that shot like the one I got, the reviews would have been much different. After 2 weeks in the shop...
