Vfc gbbr’s are supposed to be really good, I haven’t owned one so cant give an opinion.
if you want a cheap -stick your toe in
GHK’s G5 is really good, and nice and lightweight with nice recoil
it runs m4 mags, which are expensive to buy new, feedlips have a tendency to shit the bed (they crack) if hamfisted loading is carried out. DevilHunter makes cnc feedlips, expensive but will outlast you!
Failing that, TM’s MP7 is also supposed to be superb
just a couple of options over an MWS
Or try something a bit more “out there”
Ghk AUG, VFC FAL etc
