any updates?

wow impressive, want to see that working

me gusta nice gun man

so simple but so nice now make it so it have more power for your steel bb's

why would a single be easier, are there any differences? lol, that is some basic pneumatics... a single one is much easyer because it has only one pilot side, the oter is exaust (waste air from the piston) also you need a les complicated (3/2 ventil (dont know te right word)), a double action pisto...

nice may be my next one i'm not sure

nicly done! now make a video

LOL simple solution indeed xD

they are not that expensive, i got mine for like 8$ look on ebay ^^

that sucks!
solution: go for a full metal qev gun no gleu problems xD

looks good why 2QEV's?

red or bleu cammo would be cool, or with some yellow, i dont remember the name ;p or dip it in a large bath of plasti dip xD

allright keep improving it!

hmm why does your barrel go up when you fire it? in that way it is not that accurate

that would be better mrcrowley! also a bit safer in my opinion
