G@P M4A1
 

I bought a G@P M4A1 and it has never worked correctly. it fires in single but it dosnt seem to want to feed in full auto and it seems to be having a dud shot every second shot.

what do u guys think of this gun and did anyone elce have this problem?Attachment 3738

Well could be a number of things. Did you buy it new or used? How many rounds have you fired with it? Have you upgraded it? Has the hop-up ever been replaced((big one here)).

Also, but maybe least likely what make mags are you using? And how old are they?

you might want to check the wirging...

i bought it used, its a stock G@P upgrade.... all metal 190 spring, and metal air nozzle.... which i think is the problem. I have replaced the hopup multiple times.

sorry this post should be in technical issues. plz move if possible.

lube the mags? tried different brands of mags? try replacing tappet plate? feeding problems are really hard to track down

I would change the nozzle, I would missfeed untill I switched mine and things went good after that
