The action "Blocks the sear" maps to which M240B feature?

• A. Length of the firing pin
• B. Belgium
• C. M240B applied safety
• D. 1100M

Answer: (C)

The action of blocking the sear describes how the safety on the M240B prevents the trigger from releasing the firing mechanism. When the safety is engaged, it physically blocks the sear, stopping it from moving and thereby preventing the hammer/bolt from being released to fire the weapon. That direct mechanism—the applied safety blocking the sear—is what the option refers to, so it’s the M240B applied safety. The other options don’t describe a safety function: the firing pin length is just a dimension, Belgium is the country of origin, and 1100M is unrelated to how the sear is blocked.
