The MMG is designed from the ground up, to be a compact, lightweight, and low recoil automatic weapon for use in the assault role and is one of the lightest in its class.

The belt-fed Stoner MMG features what the company claims is a unique action spring interaction, which removes the need for a stock-housed buffer system.

The top of the receiver and fore-end are fitted with lengths of MIL-STD-1913 sight rails together with an M-LOK compatible fore-end. The gun features a quick-change barrel facility and the barrel release catch is located on top of the receiver to prevent inadvertent barrel release.

As the stock does not contain any recoil or buffer mechanism, any form of stock design can be fitted to the rear of the receiver to meet desired operational configurations. The belt-feed is from left to right and the centrally-mounted feed mechanism is fed from below via an ammunition container, which is secured to the underside of the receiver by a further length of MIL-STD-1913 rail. The location of the feed mechanism avoids the problems inherent with traditional feed-tray designs that require the tray to be raised and lowered in the loading process, and do not by default, generally provide a secure sight base for optical and other sighting devices.

With the Stoner MMG design, optics or other sighting devices are securely attached to the sight rail, which is integral to the receiver.
