Pollynator_bravo2 Posted February 16 Share Posted February 16 Afternoon, Ive been looking at my mates TM MP7 aeg. He brought a couple of new mags hi cap ones and they seem to reduce the performance of the gun to 100fps. The only modification he’s done to it is to adapt it from the odd tm battery adapter configuration which I think was a 7.2v battery over to a tamiya lipo 7.4v. if it’s the mags I’m not sure I can solve that one. anyone else had a similar issue?

Moderators Tackle Posted February 16 Moderators Share Posted February 16 Could they be slightly misaligned with the feed nozzle to the hop ?, not enough to stop them feeding but just enough to move the hop a fraction, causing a loss of air seal ?

How would I check that? There is very very little play when they are in so it must be a design fault I’m guessing Link to comment Share on other sites More sharing options...
Moderators Tackle Posted February 18 Moderators Share Posted February 18 Only way would be to precisely measure them, compare the new mags to the old ones, ideally with a decent vernier caliper. Link to comment Share on other sites More sharing options...

Nick G Posted April 18 Share Posted April 18 Does the fps go back up when an original TM mag is used ? If so , there's your issue, the aftermarket mags. Link to comment Share on other sites More sharing options...
