I just bought a Mauser SR, and I am wondering how I can upgrade the gun to make it more accurate. I was talking to a man at a local airsoft store and he was saying that I would need to buy a new cylinder, trigger box, and other things if I wanted to buy a new hop up and inner barrel. Can I not just buy a tightbore barrel and hop up? Also, what kind of barrel and hop up would work with my gun? I'm not really looking for more fps, just more consistency with the shots.

Thanks
