Which component is associated with PPF on the SCAR-H MK17?

• A. Gas tappet
• B. Firing pin
• C. Auto safety sear
• D. Trigger bar

Answer: (C)

PPF is tied to how the trigger release is managed in automatic fire on the SCAR-H MK17. The auto safety sear is the part that interacts with the firing mechanism to control when the hammer releases, enabling or disabling automatic fire as determined by the selector. Because PPF hinges on that controlled release, the auto safety sear is the component associated with it. The gas tappet belongs to the gas-driven cycling system, the firing pin simply strikes the primer, and the trigger bar just transmits trigger movement to the fire-control group—none of these directly handle the sear release behavior that PPF requires.
