I have a G and G M4, got it in a trade. I fixed the motor grip, fixed the dust cover shimmed it and disabled the blow back(still have all the parts), gave it the best possible air seal with stock parts. Shooting at just under 400 with .2 gram. Has built in spring release, great feature for saving your gearbox life. Gearbox was in excellent shape, the original owner was a chairsofter. So the gun is in like new condition.
It started life as a ASGI PWS diablo. The person before me installed a ics pistol front end on it. Also can make a longer barrel for it and install a madbull mock suppressor that quick detaches and uses a special flash hider(believe it is called a G5) . Willing to trade you for the gun with mags, and maybe some cash depending on what shape it is in. For pics txt 480 773 0335.
I saw that you have a echo1 contractor's AK, willing to work that possibly into a trade, if you still have it.
