Chassis

The GMG features a robust receiver and mounting interface designed for tripod or vehicle integration, providing stability and durability in sustained use.

Operation

It operates using a recoil-operated system to cycle ammunition reliably during extended firing sequences.

Slide

The GMG does not use a slide; instead, it employs an internal bolt and feed mechanism within the receiver to chamber and extract cartridges.

Maintenance

Routine maintenance involves clearing the system and cleaning and inspecting the barrel, bolt assembly, and feed components to ensure dependable operation.
