The SFMG Mark 4 was a general purpose machine in every sense of the word, generating only modest interest and light sales overall - the only customer becoming Indonesia. Becoming the company's last attempt at a small arms design, the SFMG was an unspectacular yet adequate general purpose machine gun offering up varying rates of fire depending on the operator's configuration choices (700 to 1,000 rounds per minute).

Standard issue operation saw the SFMG fielded with a conventional folding bipod system for basic support a light-weight barrel assembly. The machine gun fired from an open bolt position to prevent the ammunition from "cooking off" by the heat generated from each successive firing action. Being of a belt-fed design, the SFMG looked every bit the part of a light machine gun system, fitted with a conventional gas-operated piston tube and firing the NATO standard 7.62x51mm cartridge to good effect from a 49-round ammunition belt. The SFMG could also be mounted onto a tripod for heavy-duty suppression fire and maintenance of the weapon was light, requiring little in the way of tools in the field.

The SFMG Mark 4 series was never accepted into any serial production of note.
