AK-47 Firing problem.

[Vivisector]

My TM AK-47 worked fine for a couple of years. Never opened it, never upgraded it. Everything is still stock.

I went to a game earlier in the season and went to test fire. The gun cycled once in full auto without firing a BB, then stopped. Every trigger pull after it just made a click that I could feel through the pistol grip, as though the gears refused to move. Thinking that something must have come out of position in the mechbox, I disassembled it. No damaged parts. I reassembled it (after a lot of "WTFing") and it worked. For two mags, BBs firing and everything. Then the ugly problem reared its head again. Another dissassembly and reassembly yielded a working gun, but again for only two mags.

As this is my first attempt at working inside a mechbox, I need some clue as to what could possibly be wrong. Any help would be appreciated.

have already tried checking your contact swithces?

also, there's this part that is screwed on the gearbox just under the sector gear.... try checking that one out if it's loose or not.... the movement should just be to the fro... there shouldn't be any wobble of some sort.... while you're at it... also try checking your selector plates....

I'm 100% sure it's not an electrical problem. The motor is running, even when not connected to the mechbox.

Doctor time, because there's no valid reason it should jam so much.
