The DFSG uses the same mechanism as which common device?

• A. Rifle
• B. Crossbow
• C. BB gun
• D. Air pistol

Answer: (C)

The main idea here is a propulsion method that stores energy and then releases it in a quick burst to push a small projectile through a barrel. The DFSG uses that same simple, stored-energy propulsion as a BB gun: a piston or valve compresses air in a chamber and, when triggered, releases the air to shove a tiny BB down the barrel. This is different from a rifle, which relies on explosive ignition of a cartridge, and from a crossbow, which uses stored mechanical energy in the limbs. While some air pistols also use compressed air, the most direct and common-device parallel for the DFSG’s dart-propulsion mechanism is the BB gun.
