Clearing Procedures for the M4 Series Weapon

The first step in maintenance is to clear the weapon. This applies in all situations, not just after firing.

This paragraph explains the techniques and procedures for clearing the M16-/M4-series weapon. Additional mechanical training is available in TM 9-1005-319-10 to include disassembly, maintenance, assembly, loading, and sight manipulation.

WARNING: To be considered SAFE before disassembly, cleaning, inspecting, transporting, or storing, the weapon must be cleared.

NOTE: Get a buddy to witness and verify all steps of clearing procedures.

  2. Remove the magazine by depressing the magazine catch button and pulling the magazine down.
  3. To lock bolt open, pull charging handle rearward. Press bottom of bolt catch and allow bolt to move forward until it engages bolt catch. Return charging handle to full forward position. If you have not done so before, place the selector lever on SAFE.
