One for the Pros to venture forth on. XMT Body not getting into the rhythm.

You're right. I didn't thoroughly read the answers to my own questions. Good catch.

Fresh RT PIN Anyone. The center one is from my Retro Valve. Same size, and looks truer to form.

[OPBN]

Yeah that pin on the left is definitely bent. Try swapping the on/off into the X and see what happens.

[nak81783]

WAIT! If we don't figure out why, it might just bend the other pin.

[nak81783]

Concerning the on/off bottoms in the picture, is the left one the one that was in the pneumag?

[OPBN]

Probably forgot to pull the trigger when pulling the X out and bent it.

[XtraKargo]

The cause of the bent pin may be from my Pneu and when I release the Valve. I have to unscrew the body as well as the valve then push the pin the rest of the way.

The Retro wouldn't have that issue.

Yes.

I'll look at my on/off bottoms tonight. I don't think they're that chewed up. LPR too high? I don't have a pneumag, so I don't know. It might be simply from use and rate of fire.

Why it worked in the ULE but not the XMT, I'm still not sure. Are the holes that the on/off pin goes through in the same spot relative to the rail bushing? Are they the same diameter? Do you see any wear around the XMT hole that's not seen on the ULE? Or maybe the ULE has been beat into submission?

I think OPBN can share in this pain I left the sear out one day and caused that issue. Full auto and sheared a pin.

This is my only understanding of a pneumag. Is yours set up differently? I need more details. How did this happen? And why does the bent pin still work in one body and not the other?

I did do this one as well. Couple of suggestions on the pneu. Drill a hole in front of the FS screw. It will allow you to use an Allen key to push the back of the sear up and degass the valve. Another option is to take a grip panel off and manually trip the sear before trying to disassemble.

I am learning this tip during all this testing actually, much easier. I will remember it for sure.

No sear left the pin to do what it wanted, bouncing inside the frame. Plus like a dumb dumb, I kept thinking it would come out of it somehow (thinking the FullAuto effect was interesting) and gassed up and degassed 3 times before I noticed the sear on the bench.

May be similar in function but not the same setup. I got a cheater from the first production with Zap a few years back.

Why doesn't it just bleed off like normal when the tank is unscrewed?

Or do you mean just to push the on/off pin up, so the valve can be removed?

Still don't understand why the bent pin worked in one body and not the other? Must understand why...

[XtraKargo]

On a Pneu without air to trip the Pneu the pin remains down when the marker is degassed.
On trick I have been doing is as I am degassing flicking the trigger since and it pushes the pin back up. Not always reliably thou.
