What type of firing mechanism does the M16 utilize?

• A. Blowback
• B. Gas-operated
• C. Recoil-operated
• D. Hammer-fired

Answer: (B)

The M16 utilizes a gas-operated firing mechanism, which is a key feature that distinguishes it from other types of firearms. In a gas-operated system, the firearm uses the energy from the gas created by the ignited gunpowder during the firing process to cycle the action, eject the spent cartridge, and load a new round into the chamber. This method is efficient because it allows for rapid firing while maintaining lower recoil, resulting in improved accuracy and control. The gas system operates by diverting a portion of the gas through a gas port located in the barrel, which then travels back through a tube to push the bolt carrier group rearward. This action is necessary to chamber the next round. This system is particularly suitable for the M16’s design, contributing to its reliability in various conditions and enhancing the service rifle’s effectiveness in combat scenarios.
