CA M4 not feeding full auto properly.

[Sonnikid]

Lately I have noticed when I try and fire my CA premium sportline LWRC M6 on full auto all my mags only feed around one in 5 shots, semi auto feeds every time and I know its not the mags because my brothers M4 feeds every time on the same mags. Any suggestions would be helpful :S

Re: CA M4 not feeding full auto properly.

I had this issue recently after building a custom m4. The problem more than probably lies with the hop up. either the rubber has split or is just worn. also check the hopup unit itself isnt loose, as if it can move back or forth it will have an effect on the feed.
