I was using this as a DMR project but I don't have the time or money to continue right now. The gearbox is stock and has been re-wired to the rear. The barrel is an S-hopped madull 6.03 with a flathopped G&G green bucking and a modify flat nub. It was shooting just fine but it has some hiccups now, I suspect it's the bucking causing the issue because it is pretty old and worn out. The only other thing is the safety sticks, so I leave it on fire and just disconnect the battery between games. Comes with 6x 100rnd mids and 1x 50rnd low and an SSO RT-33 sling. $250 + shipping and PP fees.
