User:XW3 AR3 L3GION/M118 Assault Shotgun

The M118 Assault Shotgun, abbreviated as the M118 AS, is a 8-gauge selective fire shotgun, introduced in 2578 to replace the aged M90 CAWS.

Design
The M118 is an air-cooled, gas-operated, self loading semi/full automatic 8-gauge shotgun designed for close-quarters action alongside the MA5AR-G. The M118 is the first shotgun used by the UNSC to use the bullpup configuation as well as the selective fire mechanism. Like the MA5AR-G and the BR66HB-SR, the M118 has a built in electronic suite detailing the amount of ammuntion left in the weapon and the type of ammunition as well as other information including limited navigational data. Like all UNSC weapons, the M118 can connect to the HUD or the Neural Interface of a soldier and display a targeting reticule as well as other tactical information.

Visibly, the M118 in now way resembles the M90 CAWS, instead in follows a layout similar to the BR66HB-SR. The M118 uses a twelve round magazine that fires the Soellkraft 8 Gauge Shell as standard but can also load a twenty eight round magazine for longer firing periods. The M118 AS can empty its twelve round magazine within eight seconds and the twenty eight round magazine within twenty seconds. The M118 can also fire several different rounds to diversify the weapons destructive capabilities, such round include:
 * Lehto Incendiary Shells - the LIS refers to a zirconium-based pyrotechnic shotgun shell round that produces a high-temperature short range (LIS rarely exceeds five metres) flamethrower. However the LIS produces such little recoil, that the M118 must be re-pumped to eject the empty casing.
 * FRAG-14 High Explosive Fragmenting Armour-Piecing Shells - the FRAG-14 HEFAP refers to the 19mm fin-stabilized miniature grenade that arms three metres after leaving the barrel and has an effective range of 200 metres. The FRAG-14 is considered a anti-personnel weapon due its frgamenting nature, making it capable of destroying energy shields and penetrating armour up to four centimetres thick.

The magazine is fed into the stock of the weapon and the handgrip must be pumped once to load the first cartridge into the breech before firing. The M118 has a selective fire mechanism allowing the user to fire a singular shot or become fully automatic at the pull of the trigger. The weapon has little recoil as most is absorbed into the weapon, allowing the user to mantain his target even after firing several shots. The M118 can also have several attachments including an suppressor, a vertical grip attached to the handgrip. While intended for the soldier of the UNSN Marine Corps, the M118 AS has been used extensively by Naval bridge officers, where it is kept under the officers desks in case of enemy boarders.

Quotes
"The M118 AS is a powerful weapon, those CQB guys are mad - I've seen one wipe out a entire pack with just one mag. "

"The LIS turns the M118 into a mini-flamethrower, capable of burning the hide of any Neo-Covenant."

"I was armed with a mag full of those FRAG-14 HEFAP rounds, the Neo-Covies tried rushing me in those Choppers. Seven minutes later, they were smoulding machines with bits of the riders."
