Gas blast, auto only describes which aspect?

• A. Feeding method
• B. Safety mechanism
• C. Locking system
• D. System of operation

Answer: (D)

This is about how the firearm cycles and operates—the system of operation. Gas blast points to a gas-driven cycling method, where the energy from fired gases powers the action to eject, chamber, and re-cock for the next round. The phrase “auto only” confirms automatic fire capability, but the key idea is the mechanism that drives the operation itself, not how rounds are fed, safety features, or how the bolt locks. Feeding methods relate to magazines or belts, safety controls govern discharge prevention, and locking systems describe how the action locks during firing. So the aspect described is the system of operation.
