Which MG3 feature is used to block the sear?

• A. MG3 Practical Range
• B. MG3 Applied Safety
• C. MG3 PPF
• D. M4/M16 Type of feed

Answer: (B)

Blocking the sear is a safety action that stops the firing mechanism from releasing. The sear is the part that holds the firing path in a ready-to-fire state, and engaging the safety interrupts that path so the weapon cannot discharge. On the MG3, the applied safety is specifically designed to physically intervene with the sear’s engagement, so when the safety is on, the sear is blocked and firing is prevented. That’s why this feature is the one used to block the sear. The other options don’t affect the sear: practical range is just a performance spec, the PPF option isn’t the sear-blocking safety, and the feed type relates to how ammunition is supplied, not the firing control.
