M43 HD Shotgun

M43A
The M43A Heavy Duty Shotgun was designed for the SPARTAN programm though the first prototype was not created until after the battle of Reach on Earth. IT was passed upon SPARTANS combat experience of finding the shotgun slightly underpowered against zealot and ultra ranked elites. The M43A resembelled a cross between a gataling gun and a double barreled shotgun, having 5 gun tubes, each one flips open near the gun body and 5 shells can be inserted, usually by a quick loader. It wasn't designed to be accurate, being wielded underarm though some models had laser sites or HUD links attached to aid.

M43C
The M43C was a technical marvel. It was almost a complete rework of the original, being closer to a gataling gun than its predecessor. It consisted of the main barrel assembley, a rotating set of five barrels, the ammo box, holding 15 shells and the main driver that consists of two main parts, the electric motor for the rotary barrels and gas operated laoder for the shells. They weapon preformed admirabley in combat but was rarely used due to its weight. It was only capable of being used by a SPARTAN in MJOLNIR armor of a marine gunner team using a tripod or bi pod. Recoil is minimal thanks to compensators in the butt.

The weapon as a whole was quoted by a SPARTAN as 'we needed something to blow a zealot in half rather than them cutting us in half. This is just the gun, and it can pop any other elites who get in our way...'
