The chamber should be cleaned periodically with the chamber cleaning brush. The following procedure is used with the rifle ASSEMBLED and the magazine removed and the safety on. Screw the threaded end of the cleaning rod section into the ratchet base of the brush [see figure 6a]. Pull the operating rod handle rearward and engage the bolt lock to hold the bolt back. Apply a light coating of bore cleaner in the chamber. Insert brush into chamber. Pull the operating rod handle rearward to release the bolt lock and slowly allow the bolt to move forward to push the brush into the chamber. Move the rod section up and down several times to scrub chamber interior [see figure 6b]. Lock the bolt to the rear. Grasp the brush handle next to the receiver and remove the brush from the chamber. Use a clean patch to wipe the chamber. Repeat with clean patches until patches come out clean. Do not oil chamber as chamber was designed to operate dry.
