Gas blast, auto only refers to which weapon?

• A. M16
• B. G36
• C. M249
• D. AK-47/AKM

Answer: (C)

Gas blast describes the visible venting of propellant gases used to cycle the action in a gas-operated firearm. When a weapon is designed for automatic fire only, that gas-driven cycling—and the associated gas venting—is most noticeably tied to its auto mode. The light machine gun in this list is built specifically for belt-fed, sustained automatic fire and is commonly described as auto-only in training contexts, so the gas blast you’d observe is associated with auto firing of this weapon. The other rifles and the select-fire option on some variants can operate in semi or auto, but they aren’t typically described as auto-only in standard training materials, so they don’t fit the description as cleanly. Therefore, the gun this item points to is the one designed for automatic fire only.
