FWIW:
The price is consistent with what I have seen around here. The real question is why do you want it?
For hunting, I never felt the 100s were very well respected.
For collectors value? Then be real careful, cuz minor imperfections can destroy value.
FOr plinking with surplus ammo? Then buy it. Semi-auto 308s are pretty spendy in military configuration. For $350 it should be a fun gun.
Just my 2 cents . . .
Others here can give you better information.
