G&P sentry issues

[Ducky]

Right so i got a new G&P sentry used it a couple times now and for some reason it seem the mags arent feeding. Now at first i thought it might be the mags so i got some new ones and the same thing is happening. It fires occoasionaly but then stops feeding i take the mag out they release bb's fine put it back in nothing. Any ideas?

Mine got jammed up in the hop with a certain brand of BB's.

Changed brand and all was hunky dorey again.

Hmmmm doesnt seem like a jam. will try some diffrent bb's tommorow. I was wondering weather its got anything to do with the way the mag sits in the magwell.

Is the nozzle moving backwards and forwards like it should? If you take the mag out and look up the feed tube into the hop unit, you should see the nozzle pop back then forward again when you fire.

have a look over your hop rubber , strip the hop down give it a clean and look for any damage and rebuild

Worked out that piston isn't moving all the way back to let the mags load into the chamber.

Booyakasha.

Could be a broken tappet plate. If it sounds sketchy it may be middle piston teeth or even sector gear teeth have detached themselves.

Either way thats a gb out job.

Could be the sector gear axle - I have had them go on both my G&P M4's
