Sniper rifle?
The pistol grip is way too small, the barrel is short, and most everything else looks out of proportion.

I agree that the grip is a tad too small, but as far as the proportions go, it is meant to be large and bulky, its supposed to be a fixed weapon that can only be fired while it is stabilized by the bipod on the front. Would take a team of 2 or 3 marines to set up and fire. Or one Spartan could carry it as well, though it would still need to be mounted to fire.
