"I got this gun, mostly because i knew i'd be able to fix it up. I was expecting multiple problems with the gearbox or receiver. But i got lucky! There are only 3 problems i found with it:
1) small crack on hand guard [not a big deal]
2) gun stuck in semi-auto [unscrewed the selector switch, 1 spray of WD-40, it works in all shooting modes now]
3) hop up adjustment tab is broken [i used a toothpick to adjust it, works fine]
Overall, this was a great buy! bought it for $39, came with a battery, unjamming rod, foregrip, and magazine. The same fully functional gun goes for $117, i saved $78 dollars. Definitely worth it!"
