Which of the following does NOT apply to a multi-barrel type weapon?

The correct answer is that a multi-barrel type weapon does not fire sequentially using a single bolt assembly. In multi-barrel systems, each barrel typically has its own firing mechanism or bolt, which allows for simultaneous firing. This design contrasts with single-barrel weapons that rely on one bolt assembly to fire the projectile, resulting in sequential rather than simultaneous firing.

Multi-barrel weapons are engineered specifically for higher rates of fire and enhanced firepower, making them effective in combat situations. Options that describe simultaneous firing, a higher rate of fire, and the use of a rotary mechanism accurately represent the characteristics of multi-barrel weapons, while the concept of sequential firing with a single bolt assembly does not align with how these systems operate.
