M7S SMG

"The suppressed M7 -- tears through armor and turns bad guys into chum."

- Gunnery Sergeant Edward Buck

The M7S Submachine Gun, sometimes referred as the Suppressed or Silenced SMG, is a personal defense weapon issued to UNSC Armed Forces special operators.

Design details
A variant of the M7 SMG, the M7S is equipped with an external flash and SS/M 49 sound suppressor on the barrel along with a flashlight. To assist the user in target acquisition, the weapon is fitted with a SLS/V 5B smart-linked scope. Muzzle flash is significantly reduced, and firing the weapon gives a barely noticeable sound, increasing stealth applications for the M7S Submachine Gun and increasing accuracy from decreased recoil, making the weapon more efficient at medium-long range. It fires 5 x 23mm M443 Caseless Full Metal Jacket from a reduced 48-round magazine.
