i had some difficulties with my G5. not only are the mags bloody hard to load (actually got cramp in my forearm trying to force the 20th bb into the mag) but the accuracy of the rifle wasnt too good. the hop up couldn't lift a 0.25g BB unless it was all the way on, and even then, half the BBs seemed to ignore the hop all together and just drop.
Ive put it down to a filthy barrel, as i cleaned it when i got home and it was minging, as in, white tissue in, black tissue out, so hopefully it'll be better now. i want to try it but i dont have anywhere longer than about 5 metres to shoot at home.
but having said all this, it was still bloody fun
EDIT:
Also, If i move over to using straight propane, can i simply avoid faffing around with adding silicone in the bottle and ensure that whenever my mags are stored they have some Abbey maintenance gas in them? if it works how i think it will, the seals will slowly dry throughout the skirmish day when the magic gas is swapped for propane, then at the end of the day, swapping back to magic gas re-lubricates the seals... right?
how fast will the seals dry out and start to leak if dry propane is used?
