Not really giving us much to go on there!

Are they jamming, not feeding from the mag or what?

Re: hop unit

is it a madbul ultimate?? if so 1st check the nib as sometimes its too big so hop always on, 2nd check its not catching on the upper, i had to file mine to allow it to slide back onto air nozzle

Re: hop unit

i would remove the hop/barrel and look down it to see if any hop is on when it fully off, also check the rubber is fully seated on the barrel and that its not being pulled forward as your pushing it in
