Which describes MG3 System of Operation?

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

Answer: (A)

The MG3 uses a recoil-operated action with gas assist and is an automatic-fire only weapon. Recoil operation means the barrel and bolt recoil together for a short distance after firing, then unlock and cycle to chamber the next round. The gas assist taps propellant gas to help drive the operating parts, improving reliability at high rate of fire. This fits the MG3’s role as a belt-fed, fully automatic 7.62×51mm machine gun. The other descriptions don’t capture how the gun cycles or its firing mode: semi-auto isn’t how the MG3 is issued, and blocking the trigger bar or just noting the caliber doesn’t describe the system of operation.
