ID help - This LPR on my Spyder

[ChoSanJuan]

Yes, I said LPR on my Spyder.



It's adjustable, but not rebuildable like a Jackhammer. I'm starting to develop small leak on the vent hole but I don't know which one this is and how to tear it down. Any info is welcome!

I don't know what that is, but I would imagine that you can replace it with a Trilogy LPR relatively easily if you need to.

Pretty sure that the Trilogy LPR will screw right into where the LPC goes. Should shorten the overall package.

Looks like a Palmers rock reg.

The striker and bolt are disconnected.

The striker still functions as a semi-auto blowback.

There is a 3-way on the trigger controlling a ram that moves the bolt.

Pnuematic closed-bolt, blowback.

It is definitely an early Rock, and it is in fact rebuildable. The front plug can be unscrewed using a quarter. That gives you access to the piston. The rear section, which contains the reg seat, is kinda tricky to pull off, but usually doesn't have to be.With the problem you're describing, you should just have to replace the piston oring.

Not that early if it has the slotted end cap.

All that was lost in the 2.0 crash. Let me whet your whistle with this link to a shooting video I did with it...

BOOM! There we go! I had a feeling it was a Rock but it looks different than the current gen ones. I couldn't seem to find a 100% match. I'll try to get it taken apart with your method. Thanks everyone!

This raises so many questions for me....lol.

About an LPR? Yeah, that's why I asked the question.

Ok, thanks again for the info. The front plug didn't have an oring at all. Added it to that piece. The reg seat was not doing so well so I replaced that one too. Slapped it all back together and aired it up. No more leaks!

What in tarnation?! That thing literally is a Spyder clone AutoCocker I'm so confused how this works well, but it does ahhhhhhhhhhhhh!

I've been thinking about what you've said and did more research. While the threading isn't the same, it's just close enough. I may throw this on my sto and get a trilly lpr based on your recommendation!

Not quite an Autococker since there isn't a back block. The ram is essentially direct drive as it's mounted just inside of the rear of the upper tube. The bolt and striker cycle independently of each other but the striker is still blowback. Like an Autococker, the pneus work exactly the same and are actuated by the trigger pull.

This is awesome. I was thinking of something similar but keeping it open bolt and the trigger disconnected from the sear. The closing bolt would trip the sear somehow. That way it would be a purely pneumatic trigger.

Rock LPR's are super easy to work on.
