Thanks a lot everyone for your input, i do know what the steyr AUG is and i haven't looked at many, but i've heard CA's is pretty bad-ass, so maybe I will look at that, the price range is kind of unconfirmed, and i think i could make exceptions if it's going to last long, atleast longer than 2 years without breaking. However, if any one else sees this thread, more input is welcome and i wouldn't quite say case closed yet.
Thanks again.
Oh i notice i said under 600$ is necessary, however i might be able to push to 650 or something
