The only things I can see to adjust are to make the clip-magazine-thing bigger and reduce the size of the what I assume is an ammo counter.
The reason for the larger magazine size is for the LMG setting. LMG's are suppost to put down lots of fire so the rest of the squad can move. At the size you have it at you're going to run out of ammo pretty fast. As for the box on the top decrease the size slightly and mount a scope unless a built-in Gun-cam is already present. Other than that it's a rather nice looking gun.
