As I barely have enough to make rent, car insurance, and car payments, pretty much everything including another Mosin-Nagant is out of the question. However, here are my top eight:
Barrett M82A1 or 95
Full-auto short barreled Uzi, folding stock
RPK
L85
VEPR
Glock 18
Steyr TMP (with silencer)
Steyr PSS
