TM Mp5K FPS magazine Issue

THe_Silencer · December 3rd, 2010, 20:03

My mp5k is shooting low 200ish fps. When i push the mag all the way in, it shoots 360ish fps like it should. Seems to be doing this with every mag I got. Any idea how to fix this issue?

1) did you replace any of the internals such as the nozzle?

2) Check to see if your catch is worn. You shouldnt be losing air thru the feed tube as the nozzle should push right up against the BB, but its something to check anyways

Yeah most of the internals have been upgraded. I had a King arms mp5k nozzle installed. Reinstalled the Tm nozzle, same thing happens.

Mag pressure would move the hopup unit, so my guess is that the problem lies with hopup unit to mechbox seal.

buy a new mag release make it sure it has one of those hard springs, so the mags wont get loose and tighten up the screws on your receiver so it would have a good fit for your magazine. Hope this helps, this is common with mp5's because some brands have looser mag release and some people put tapes on top of the mag to tighten up the mag but its not really a good idea because in the long run it loosens the receiver.

Thanks Cjboi, I realized that tightening all the screws on the receiver made a huge difference.
