Need help! Classic Army G36 performance issue
 

Hi, I have a Classic Army g36c and it worked fine for a while. Then something was weird so I took the gearbox apart and then everything was fin, the gears spun properly the motor spun fine and everything. So I put the gearbox back together, then I put it in the gun, screwed everything and done. I just fired it just to see if it shot, and the rate of fire was fine! So i put my magazine in and gues what? The bb's went only 1 feet and fell. I was like WTF! So I took it apart again, and EVERYTHING WAS FINE! So I checked youtube to see if I put things back properly and I did. I don't know whats happening so please help!

You didn't accidentally pinch the battery wires between your hopup unit and mechbox, did you? That'd prevent the hopup unit from making the nozzle properly and you'd be losing air all over the place.

Did you put the tappet plate spring back in? That sounds like it could be caused by the tappet plate spring missing. Otherwise there is some serious compression issue, where the piston head is getting 0 seal in the cylinder.

I'm not lying to you and I have no need to lie cause I need help. Everything is in the correct place, and the rate of fire and everything is just perfect! The wiring could be, lemme check.

Yeah that sounds more like it then. Something is causing something to be misaligned and not getting good seal.

I looked at EVERYTHING and moved some wires a little and it still doesn't shoot properly. The bbs just comes out of the barrle and drops.

kinda have the same problem w/ my ak. thee bb's just drop out of the barrel

YEAH! Thats my EXACT problem except my rate of fire sounds fine. For my shooting, it sounds normal but the performance not so much. For mine the bbs all "drop" every shot i take, so around 12 bbs "drop" a second. I NEED A SOLUTION!!

have you try the hop up??

a gundoc told me that its probably the hop-up rubber is torn

Yeah, hop up could be entirely on, and blocking the barrel

Try the Hop-up rubber, I had an old TM MP5 that had this problem, i sold it for $100 thinking it was dead, the buyer then told me he fixed it with an new hop-up rubber. So try that.

Thanks guys, ill try it

I tried, and I fiddled with the hop up and I took it apart and did stuff with this circular rubber thing and guess wut? The bbs don't drop but they shoot 2 feet now! but not even close to what it used to shoot like. PLease help, cause i dont this its the hop up!

OK two things, first adjust hop up by turning it off (Opposite way oof the arrow inscribed on the wheel) then turn it slowly bit by bit and fire a round each time until your BB's are flying straight.
If That didn't work then disassembled your front end and check the hop up rubber see if it is torn or worse yet see if it is sitting properly in the grove (the little slit in your barrel)
