second problem, a galaxy mp5 hi cap mag of my nephews seems not to work right im winding it and its clicking but nothing is happening when the trigger is pulled ive had a quick look at it and everything seems fine, is there any defects with these that can be easily solved?

RE: mag, it needs a minimum of 20 or so bbs in it to work, make sure there are enough to tension the spring.

shimming basically involves small metal discs either side of the gears to keep them aligned, too few and your gears will wear prematurely, too many and there will be too much friction, what kind of weird sound are you getting? Is the air nozzle moving back and forth? have you tried adjusting the motor adjustment screw? bad shimming will cause weird sounds, but wont stop the aeg firing.

It is moving back abnd forth the sound is almost a pure electric motor and a slight grinding of the gears, theres no thump so to speak like I usually get
im going to give it another shot tonight and if not someone will be paid to take care of it. the biggest pain in the ass is when i reassemble the mechbox I have to put the whole aeg back together to test it then restrip if anything is wrong.

that really does sound like the motor adjustment screw, at the bottom of the grip, there's a big screw in the middle, turn it all the way in, then about 1/2 a turn back out, then try firing it
