No Trades Asking 220$ shipped WE G39 GBB (G36) with 6 100% functioning mags and 1 parts mag. (7 mags total) G36 works flawlessly. Sends .32-.5g bbs over 200' Most fun airsoft replica I ever used The factory hop up unit start to fail on holding it's setting, so I drilled screw hole on the unit and a series of holes on the adjusting wheel. Simply adjust how much or less hop you want then screw down the screw to lock into place. So basically it's a fixed hop up once you screw in the screw. A new unit sells on evike for like 10-20 bucks, but I believe my mod is better so I never bothered to buy the replacement. I also installed a NAPAS valve which allows you to adjust the fps. Plenty of videos on YouTube on how it works and how to adjust, comes with the tool as well. All rails included, however I can't seem to find the bolts for it, so for now I'm going to say no mounting hardware for the rails. Hope to find them before I ship. I have two handguards, the g36c and the g36k. The g36k still uses the g36c outter barrel, I just ressed a amplifier flashhidder into it. The amp does have rust on it. Feel free to ask any questions
