What is the M2HB System of Operation?

• A. 1830m
• B. Gas-operated, short recoil
• C. Manual action
• D. Rotary mechanism

Answer: (A)

Understanding how the M2HB cycles after each shot is what this is about. The M2HB is recoil-operated with a locked breech. When you fire, the barrel and bolt recoil together for a short distance while still locked. After this short travel, the bolt unlocks from the barrel, continues rearward to eject the spent cartridge, and then a new round is fed into the chamber as the bolt returns forward under spring pressure to lock again. This repeating cycle drives automatic fire. It is not gas-operated, not manually operated, and not a rotary mechanism. A distance like 1830 meters describes how far the round can effectively reach, not how the action functions.
