MP5K or MP5KPDW
thats a pw version, remove the sock and flash hider and you have a mp5k.
ghe stock does fold tho so it gets smaller and the stock is handy for steadyer hots.
a cyma shoots about 360-380.
next step larget would be an mp5a6(for colapseable stock) or a5 (full stock) replace "a" with "sd" and itll have a silencer so itll be a lil longer in the front but itll hae the same stock respectively sd6 colapseable sd5 full stock.
or you could just get an Ak beta spetzna or stubby 4
