Which action is not listed in the immediate action sequence for the M4?

• A. Slap the magazine
• B. Check the ejection of a round
• C. Pull the charging handle to the rear
• D. Tap the forward assist

Answer: (B)

The action being tested is understanding what steps make up the immediate action sequence to clear a malfunction on the M4. The routine is designed to restore a round to the chamber quickly by focusing on seating the magazine, chambering a new round, and attempting to fire again. Slap the magazine ensures it’s fully seated and not causing a feed fail. Pulling the charging handle to the rear racks the bolt and ejects any spent cartridge, then releasing it chambers a fresh round so you can try firing again. In many quick-reference guides, a final tap of the forward assist is included as an optional reminder to ensure the bolt carrier group moves forward if it didn’t fully chamber a round after racking.

The action of checking the ejection of a round isn’t part of this sequence. It’s more of a diagnostic observation than an active remedial step you perform to clear the stoppage. The sequence is about applying the mechanical steps to restore function, not inspecting cartridge ejection.
