This is a repost from the AEG board because I didnt get any suggestions
My classic army G3 has no internal upgrades and jams almost every time I fire full auto. The battery is 8.4v and everything else is stock. I am using very good double polished bbs so that shouldnt be the problem. What can I upgrade to reduce the chance of a jam?
Thanks!
some people suggested replacing the hop-up, could it be anything else?
