Summit NP2 won't cock

[South Eastern Airgunner]

Hey fellas.
I disassembled my NP2 and cleaned, lube and polished everything, put it back together but then I went to shoot it but couldn't.  When I went to break the barrel, it only went down about 3/4's of the way down.  I took the stock off and put it back on my spring compressor and tried to see what was going on.  All I can say is the gas ram, for some reason, isn't compressing enough to allow the piston to engage the sear.  I've done two NPs in the last two months, but this is my first NP2.  Anyone have any ideas??  I would appreciate any feedback.  Thanks

If the Nitro Piston rod is not centered and properly seated things may bottom out before the sear can latch.

Also, there is a spring in the trigger assembly which can escape when the gun is disassembled.  Without this spring in place ti will not latch.

The sear itself should be outside the little cross piece on the compression tube.

That's about all I've got sight unseen.  Good luck finding your issue.

Thank you Roadworthy.  The tension spring is there,  it gave me a fit but I tied a piece of fishing line to keep the sear and spring in place to get the trigger pack back in then cut the string, and the sear seems to be right.  The only thing I can think is that the gas ram may not be in just right, like you said, although I'm not sure how it could be, but that seems to be the only logical answer.  The "catch" in the piston is not reaching the sear.  Thank you again for your time.

If I recall correctly, the NP2 has the piston upside down from the original NP. Can the NP2 be installed upside down, or is there only one orientation that it cam be installed in! I've never taken my NP or my NP2 apart, so I have no clue if this is even possible. I'm probably wrong, but there is a snowballs chance I might be right! LOL

Good luck getting it corrected.

Did your beartrap come loose and get jammed?

Yes, it is "upside down" compared to the original NP.  That's the way I have it in, and there is a indention in the rear block for the "rod" of the gas ram to sit in.  I've got one of my NPs and my NP2 both bottom up on the kitchen table looking to see if I can figure this out, but I don't see any recourse except to tear down the NP2 again.  Thank you for your input.

[/quote  Thank you Roadworthy.  I had too much of the sear inside the comp tube.  I took apart one of my NPs and finally put what you said and what I saw on my NP together and even watched Crosman's NP2 short video, paused it and knew you were right.  Got it all back together and it's shooting smoothly.  Thank you!!

I just want to say that I really appreciate all the feedback I've gotten over the last month or two.  From fixing an air rifle, to finding certain pellets, y'all have been great.  I truly thank all of you.

That's what we do. You're very welcome.

Hey Joe, these guys are great, aren't they!

Personally, I don't know if I would still be into airguns without them. Probably have one in parts in the closet, not being worryed about putting it back together thinking it wouldn't shoot straight anyway.

"The sear itself should be outside the little cross piece on the compression tube." Thomas this one got me twice.

I wouldn't have mentioned the sear on the outside if I hadn't had the same problem myself and spent two days trying to figure it out.  That kind of stunt sticks with you.
