(1) Clear the weapon

combination tool case is ejected. Unlock the bayonet, let it hang
vertically, and after disengaging the head of the cleaning rod from
the front sight base, pull the cleaning rod out of the rifle.

in the butt, nor does it have a cleaning rod; these are carried separately.

position and pull it out as far as possible.
