There doesn't have to be a certain type or model. Just as long as it accepts the M4/M16 Magazine it can be a SCAR, M4, or whatever. There are a lot of good guns out there on the market that you can get, it really depends on your budget as to what you should get.

Keep in that the metal guns are going to run you a little more but they are going to hold up well against being dropped, or if they are accidentally banged against something.

A lot of the guys like to start out using a Echo1 M4A1 metal body gun, as JBear pointed out. I think Nashville Airsoft has them for somewhere around the $250 mark. It's a great starter gun for the money.

ill see what i can do to get a metal bodied m4

thanks but i dont know if its my prise range>
