jg bar 10 double feeding issues

[Pfhor]

I just got my bar 10 yesterday and about every 3rd shot will be a double feed. I have tried it with 2 different magazines and put about 100 rounds through each. I think the problem comes from a piece right where the bb feeds from the mag into the gun. The piece isnt quite big enough to keep bbs out of the air cylinder when the bolt is pulled back and the air nozzle is not covering the hole. I am not sure that that piece is the problem and I will take pictures the next time I have the gun apart. If anybody has any suggestions or know the real problem please help.

when you cylce the bolt back are you cycling it all the way with out stoping or letting it go forward at all because if you stop a litte and let it slide forward then pull it all the way back to finish a cycle it can load more then one round

No i just pull it straight back with no stops in the cycle.

welp that was my idea XD if you short stroke it you can load more then one round

Alright that little piece described in the first post seemed to be the problem. BTW the piece is labeled vsr 22 in the manual. All I did is replace the week spring pushing this piece with a much stronger spring (a spring from a pen cut in half) and it seemed to fix this problem. I have put over 400 rounds through it since then and no double feeds. Hope this helps anybody else having this problem.
