k, to what extent can I upgrade a TM mp5 (HG) in terms of fps? I don't want it upgraded to 450 fps and then not have enough battery space and energy to fire it. I like my GP m4a1, but I recently fell in love with the mp5.
one more dumb question. does the tm mp5 sound like an annoying sound on semi auto? My GP m4 sounds like a very semi loud powerful stapler.
Also, it has to be on a collapsible buttstock!
thanks a bunch
