Clip, I hope Crosman doesn't send you a replacement NPSS. On my NPSS, I discovered it came without breach spacers so I tore it down and installed 5/16" brass washers (from Lowe's) where the plastic spacers should have been. Then I tightened down the barrel pivot pin/screw and it kept the barrel from drooping if I set it down harder than I should. The brass washers don't compress like the plastic ones do and shots from my NPSS is more consistent because of it. At 65 yards, I was grouping 1-1/2" with CPHPs, before the gas ram failed. I talked to someone there who had the authority to send me a replacement gas ram and I changed it out myself. My contact there even honored the warranty, even though I took the rifle apart and tuned it. It's now back to shooting and hitting with authority. If I had to hazard a guess, I'd say that my NPSS is shooting .22 cal., 14.3 grain pellets at about 730 fps. One day soon, I'll put it through the chrony.
