MG3 System of Operation

MG3 System of Operation

• A. Recoil, semi-auto, SA
• B. Blocks the Trigger Bar
• C. Recoil W/Gas Assist, Auto Only
• D. 7.62 x 51mm

Answer: (C)

The MG3’s action is a recoil-operated system that also uses a gas assist to help cycle the bolt under sustained fire. In practice, the initial recoil of the operating parts drives the cycle, and a portion of the propellant gas is tapped to provide extra impulse to ensure reliable locking and unlocking at high rates of fire. This hybrid keeps the mechanism functioning smoothly with belt-fed 7.62×51mm ammunition, especially in continuous fire. Additionally, the MG3 is designed to fire automatically only, not in a semi-automatic mode. So the best description is recoil operation with gas assist, auto only.
