Brought my ARES G36K out today and noticed that it had a minor feeding issue. The majority of the shots fire fine, some just dribble out and sometimes it just dry fires. Gun is stock besides a PDI 6.01 TBB. Tried 6 different mags, even my s-mag yieled the same results. After doing some research, people with similar problems have indicated that it could be the hop up/bucking or the air nozzle. I doubt it is the mags(which some people suggest it is). Anybody who owns one of these have this same problem/fixed it? I can't seem to find one key issue relating to the problem...
