Wow, its a nicely sized gun. Sure you aren't compensating for something?
Nah, that's not compensating for something.
I think it needs a laser sight, and a scope. And a bottom-mounted grenade launcher. And a shotgun attached to the side, with a flamethrower on the other. And a rocket launcher on top (put the scope on top of that). And a target designator for an airstrike. And it should be dual-wieldable
THIS is compensating for something.
