Well, if I could make a custom gun rather than using CrossFire, here it is.
The full idea of this gun is basically a fully automatic 'sniper rifle' (shoot very far with no bullet drop) that has no recoil.
Looking something like a Dragnuv, the barrel being larger, and the body of the gun being larger to be able to hold more ammo, it would be colored red with white camo stripes going across it with a bipod availabe for almost any situation. The gun being completely lightweight, basically a new material, would be able to widthstand everything a gun needs.
Sorry if I sound stupid, but this is my dreams..
