The DFSG uses the same basic firing mechanism as which of the following?

• A. Spring-loaded paintball marker
• B. Compressed gas firing system or BB gun
• C. Laser-based pointer
• D. Mechanical claw

Answer: (B)

The firing action relies on stored gas pressure pushing the projectile. The DFSG uses compressed gas behind a dart, released in a controlled puff to accelerate the dart down the barrel. That gas-propulsion idea is exactly what powers a BB gun or any compressed gas firing system, where a small amount of high-pressure gas drives the projectile forward.

Laser pointers don’t fire projectiles, and a mechanical claw doesn’t shoot at all. A spring-loaded marker uses a spring as the energy source and is not the same gas-propulsion method, so it isn’t the same basic mechanism.
