Well that can't be a huge air leak. I mean, even on that spring - the 110 I mean - if it's shooting 270-280 with .25s thats what? Nearly 320-330 with .2s if I remember correctly? And 290-310 with the 120 would probably be close to 350-360 with .2s. I could be wrong because I'm not really too familar with the Guarder springs, I've only used the Systema and PDI ones.
But after 10,000+ rounds (Especially continuous like in a SAW) I would definitely go with lubing up the entire mechbox internals, especially the cylinder walls, piston head o-ring, and the hop bucking with the appropriate greases.
And if you do pull the box apart, pull the cylinder out and try to run the greased piston up and down the cylinder while holding your finger over the air nozzle hole - if the piston is hard to push into the hole, you're getting a good air seal on that end.
I'm currently waiting to join the CA M249 club myself - if only they'd hurry up and release the Para.
Has anyone had any more problems out of the microswitch? Or are they doing any better?
