So I decided I might not want to go buy a support gun and find out later I hate being a support gunner. I have a budget of at most $400, mostly play field/milsim, sometimes play cqb, and am unsure about my role at the moment. I have no preferred model, and am looking for a gun I could upgrade at some point. I also would prefer to have an AEG or gas gun, I would also like for the gun to have RIS. I was looking at the JG S-System, the Cyma CM048C, and the A&K M249 full stock version.
