The BOSS is a precision instrument. in order for the boss to operate effectively it is very important your rifle remains in the same condition it was purchased. it is absolutely necessary for your rifle's barrel to remain free-floating and the action properly bedded.
This holds true for either the A-Bolt II or BAR Mark II. To check for adequate clearance, it is recommended that a piece of paper, folded once, be able to pass between the barrel and stock without any interference. If the barrel is not free-floating, lake your rifle to a competent gunsmith or send it to (he Browning Service Facility in Arnold, Missouri.

1 Clean the bore with a good powder solvent to remove all traces of powder residue. Performing this step before the application of a copper solvent will prevent the bore from refouling with copper so readily.
2 Swab llie bore with a good copper solvent using the manufacturer's recommended procedure. After neutralizing the solvent, generally with oil. il is important to swab the bore dry. Swabbing the bore dry will reduce copper buildup.
NOTE: DO NOT USE SOLVENTS OF DIFFERENT MANUFACTURERS CONCURRENTLY. A CHEMICAL REACTION MAY RESULT THAT WILL CORRODE EVEN STAINLESS STEEL BARRELS. IT IS IMPORTANT TO FOLLOW THE MANUFACTURERS RECOMMENDATIONS EXACTLY.
tered. if the rubber bedding on your rifle has been modified send your rifle to the Browning Service
Facility in Arnold, Missouri.
