Which feature blocks the Trigger Bar?

Which feature blocks the Trigger Bar?

• A. 7.62 x 51mm
• B. Recoil W/Gas Assist, Auto Only
• C. M17/M18 Applied Safety
• D. M17/M18 PPF

Answer: (C)

Blocking the Trigger Bar happens when a safety mechanism physically stops the trigger bar from moving. The applied safety on the M17/M18 is designed to do exactly that: when engaged, it interposes in the trigger path so the trigger bar can’t reach the sear and release the weapon. This safety mechanism ensures the firearm won’t fire while it’s in a safe condition. The other items don’t perform this function. A cartridge size like 7.62x51mm is just ammunition, not a safety feature. Recoil/gas-operating systems describe how the weapon cycles but don’t block the trigger path. The M17/M18 PPF is a different feature and isn’t the mechanism that blocks the trigger bar.
