the jackhammer invalidates the whole thing. Not to mention it would weigh in excess of 100lbs, require constant reloading (adding yet more ammo, and you need a sizable supply of both types) taking you into the 150+ pound range.

Remote functionality is great, but it means you have to carry a second weapon or be left unarmed, that's another 5-10 pounds for something combat effective against large foes.
