Which fire control selector settings are standard on the M16/M4 family and what does each do?

• A. Safe: weapon cannot fire; Semi: fires one round per trigger pull; Burst: three-round burst on auto-capable models.
• B. Safe: fires one round per trigger pull; Semi: weapon cannot fire; Burst: three-round burst on auto-capable models.
• C. Safe: three-round burst; Semi: automatic fire; Burst: single shot.
• D. Safe: weapon cannot fire; Semi: automatic fire; Burst: three-round burst on auto-capable models.

Answer: (A)

On the M16/M4 family, the fire control selector has three standard positions: Safe, Semi, and Burst. Safe means the weapon cannot fire; the trigger pull will not discharge any round. Semi means the weapon fires one round for each complete trigger pull, giving you controlled, single-shot fire. Burst means that on auto-capable models, a single trigger pull delivers a short three-round burst, providing a balance between speed and control and helping conserve ammo compared to full auto. Not all variants include Burst—some configurations might use Auto instead of Burst—but when Burst is present, that is its function.
