Mossberg International 81 Bolt Action - Manual (Page 12)

CLEANING THE BARREL
To clean the barrel, first remove the bolt from the rifle as explained on page 10. Moisten
a .17 caliber brass cleaning brush with solvent, and insert into the barrel from the breech
side. Cleaning breech to muzzle, scrub the barrel several times.
Use a .17 caliber cleaning rod with a clean cloth patch to wipe the bore dry. Repeat
several times, using a new patch each time, until the barrel is clean and shows no signs
of residue.
Finally, wipe with a quality gun oil moistened patch. Do not over-lubricate, a light film is
recommended.
Make sure the barrel is free of obstructions and excessive lubricant after
cleaning. Be sure not to leave cleaning patches or excessive oil or grease in the
bore as they can create dangerous obstructions. Obstructions of any kind can
cause damage to the firearm and may result in serious personal injury to the
shooter and/or others nearby.
