"Firing a 5.56x45, this baby packs a lightweight, compact punch. You fire this off and you are RUINING someone's day."

The M313 Carbine was a slimmed down, shorter, and more lightweight variant of the M392 Designated Marksman Rifle, designed by Armalite MG, UNSC. The M313 is the carbine variant of the M392, designed for use by special operations troopers in the UNSC. The M313 was along side the M392, created to be the more lightweight, tactical variant of the M392. Unlike the M392, which fired a 7.62x51, the M313 fired a lighter 5.56x45 round. It had a telescoping stock, selective fire, and an adjustable zoom scope. The M313 was also equipped with modular RIS systems for taclights, foregrips, and scopes/sights.

It came into use in 2540, and went out of use in the 2550s, being phased out with other weapons, though it was still available for civilian use throughout the waning years of the Human-Covenant War.
