Hi all,

Wondering if someone can help with this problem... I have a new-ish (~5 years) Crosman Phantom Nitro Piston CPNP22 that has stopped firing. This is a break barrel rifle ... when I break the barrel open, it's limp because the piston has already been compressed (and is ready to fire). But pulling the trigger does not release the piston... There is spring tension on the trigger pull, but it's smooth and I don't feel any friction like a break point where it would release the piston and fire. I tried adjusting the screw for trigger pull, but no change. Trigger safety switch is working. I opened up and inspected the trigger mechanism and I don't see anything wrong.

I'm sure that there's a way to open it further and to release the piston..? But I wasn't able to find instructions or guides on how to do that... Have you seen this issue before? Can a regular guy with basic tools fix this?

I found the following:

Parts list & diagram: https://support.crosman.com/hc/en-us/article_attachments/203852523

and other random web pages...

Any help or guidance would be appreciated!

Thanks all
 
If I recall I had a similar issue and turned out to be the screw that held the trigger pack in had a little lock washer in between the action and the trigger pack and with our it the seat would lock up the piston.

Another old one I had was doing this and turned out the trigger pack would only work if it was attached snug but not tight.

I know this is probably useless info but it's worth a shot.
 
This is a old disassembly of mine.

Take it out of the stock. Clamp the reciever in a vice. Maybe the spring that works the anti bear trap broke. Try pulling the linkage back and pull the trigger. You might be able to pry the sear down releasing the piston.

If not you need to take the rear bolt out holding the trigger assembly in.

Watch your fingers.
