Firing Pin Bore Brush

Keeping the firing pin bore of the bolt clean is crucial to the reliable operation of the EP9.

The cleaning task is made easy with this cleaning brush. Used together with a powder solvent, it will quickly restore the firing pin bore to a clean condition and should be an included step in every cleaning.

Insert the brush from the insertion end of the firing pin bore, give a few twists, remove, and repeat a few times. Confirm that the firing pin moves freely by removing the spring and dropping the pin in/dropping pin out.
