Separate the TMH from the body by pulling the butt upwards, cup hand over the end of the body to ensure the recoil rod assembly does not spring out.

The Recoil Rod Assembly bolt assembly and Cocking Handle.

Place the hand over the rear of the recoil rod assembly, fully withdraw the rear TMH locking pin and remove the recoil rod assembly.

Slide the cocking handle fully to the rear, disengage from the bolt carrier, continue sliding the bolt carrier to the rear and remove from the body.
