Pneumag down!

[RehKal]

So I was testing my pneumag and started having all kinds of problems. Leaking from the grip, bolt sticking, all kinds of stuff. So taking things apart I've come to realize the msv-2 is leaking, and I believe the piston that drives the sear is leaking as well. Are these parts rebuildable? anyone know what orings go in them if so?

I'm going to assume lukes trex won't fit into the emancipator m90 grip. The layout doesn't seem like it would line up at least.

Wow, one little leak and you are going to trash it all? Hope you don't break something, cause someone wouldnhave to put you out in a dumpster...

So, have you tried putting some oil down the ASA? Don't know how often you play, or when the past time this was used, so it is worth a try.

After that, i really have no clue, as i don't have a pneumag, nor know if the parts are rebuuldable, though i assume they can be. Most anything is rebuildable, dreams, a heart, a destroyed house from a storm...

[RehKal]

Well someone is ass-uming a lot. The only one talking about trashing anything is you. Hence why i asked what orings go in these parts.

- I've never seen rebuild kits offered for the MSV-2 or MPA3, that does not mean they're not out there, but I've never seen it mentioned anywhere.
- IIRC BigEvil once said he never had any luck rebuilding the MSV2 and just replaces the entire part when they fail. I'm sure he will correct me if that's incorrect.
- As far as the T-Rex fitting the M90, I didn't want to spend the time reverse engineering the frame to check if it can be modified. (It was too close just to guess) I have provided the designer with the cad models of the T-Rex so maybe he'll see this and let me know.

Hey Luke, that is what I kind of worried at. I have several MSV-2s but they seem to leaking as well. My gear/parts have all been in storage for the past five years or so. Haven't tried the other MPA3s yet, trying to solve one problem at a time at the moment. What is the overall length of the body of the trex? I'm not even sure it will fit in the M90 grip without it being milled (the grip). Taking the best measurement I can of the space inside the M90 where the trex would have to sit.. there is less than one inch of space.

See third answer above...

All frames must be machined specifically for the T-Rex with a properly located mounting tab. It is not tinker friendly.

[RehKal]

I figured as much looking at it.

[luke]

The T-Rex sits further forward in the frame than how the typical Mag frame is designed. The problem is how the frame is designed in that area on the outside of the frame, on some, the forward edge of the T-Rex will breach the outside of the frame.

This area is the concern on the M90>

The trigger pin length is what concerned me most with the trex. Can a longer pin be used on it though?

[luke]

Why would you want a longer pin?

[RehKal]

Well. So the trex would sit further back in the grip. Then again. I don't really know how long the trex is in the first place.. May not make any difference.

[luke]

The T-Rex sits forward in the frame more than the standard grip is machined, it's the geometry of the outside of the frame that may be the problem.

So i got around to disassembling the msv-2 and mpa3 today. Msv has locktite on it so was a real pain to unscrew the assembly. But the oring appears to be a 001-1/2.

The mpa3 uses an x-profile 009 oring.

So hopefully thatll solve my leaking issues... and ill have plenty of spares since they come 100 to a pack...
