The rifle it's not THAT bulky, according to the records, most soldiers liked the M-8 more than the SCAR or the HK-416 or 417, they said it was kinda more comfortable, and new materials could be other metal that stands heat, or a re-designed cooling system, perhaps by making the air flowing in a better way through the barrel so the heat doesn't cut through the grip
