Ok so I finally got around to disassembling it, i ended up being busy over the weekend. Kull I looked over the possible solutions to the issue and none of the problems you listed seem to apply to the gun. Now that i think about it, the issue is very similar to a worn/torn hop-up unit in an average aeg, but i examined the hop-up on the gun and it seems fine. The hop-up unit has a bit of damage, however, on the feed lips. A small chunk of plastic has been broken off, but I don't think that it would affect the fps by THAT much. A small O-Ring that spaced the hop-up rubber from the barrel was also torn. Oh and I also ran into some issues upon reassembling it, a can't find where to put a small spring that's 7.5mm's lengthwise and 3.7mm's width wise. There's also a small piece that looks like a small pin with a head on it (the head has clear signs of wear on it). I also found a badly beaten up and pretty much smashed spring just laying in the lower receiver, don't know how it got there or where its from. Sorry for being so beginner, but again, this is my very first gbbr. A SCHEMATIC WOULD BE VERY HELPFUL!!! if any of you have a link for one please post it! I cannot find any diagrams on google
Oh and my reason for getting a WA was because it came it a big airsoft package that I got from a friend. I sold most of the guns/accessories and already made up for most of the money i spent, thankfully.
