How do i stop my pneumag from short stroking?

Ok here goes...Sorry about the quality....http://media.putfile.com/longis-pneumag-problems

If the frame seems to be doing it's thisng and looks good internally when firing, I'd say it sounds like the sear isn't returning well enough. Are the bolts tightened down and the on off oiled well with little friction? And be sure the sear isn't resing on the piston when not firing. There should be a near-imperceptable gap between the sear and piston.

Back again have been working away from home and have not had the internet. I have a feeling you may be right about the sear resting on the MPA. I'll check it out tomorrow. All is well oiled.I may have to shave some of the metal off the piston, or move the piston further down.

unless the sear frony is hitting the top of the MPA body,, You don't have to move it down. the fact that it is high dosn't matter so much. and shave the sear leg... it's easier.

Well, the underside of the sear just touches the top of the MPA. The vetical leg of the sear is well clear of the MPA in it's rest position. I'm also going to try to increase the on/off reactivity as it's never been the same since it's been modified. It works ok, it just doesn't have the super reactivity it once had..ie...I can't bounce it so as it goes full auto anymore.

I may also try it without the QEV.

[Pneumagger]

you dont want the sear leg too far away either. I really think it may be that that you need to add shims to the ULT and/or rt on off

I'm keeping my fingers crossed!

Blimey! I think i've done it!! It seems that i needed less input pressure and i moved the MPA-3 towards the front of the gun slightly. I now can walk it dry firing but it still miss fires very slightly. I'll be putting some paint through it in a while. Now i think it's down to improving my walking technique. I think i may well buy a gauge for setting up the input pressure correctly as this should help me out in the future. I'm now going to play some guitar solo's extremely loud untill the Police turn up and arrest me! 'AVE EET!!!

[Pneumagger]

I've seen them never short stroke with paint through them, but when I take off the hopper they'll chuff occasionally.

Put some paint through it this arvo and omfg! It works put it back to back with my friends DM6 and there isn't too much difference between the 2 (unramped that is). I've just need to work on my technique now and get out and play. Thank ever so much for helping me out, i'm very gratefull (and well pleased!) IT'S ALIVE!!!
