CLEANING THE RIFLE BORE

To maintain the utmost accuracy from your BOSS®-equipped rifle, or

any rifle, extensive testing has proven that the rifle bore must be

cleaned after every 12 to 15 rounds.

CAUTION: BEFORE CLEANING YOUR RIFLE, MAKE CERTAIN YOUR RIFLE IS FULLY

UNLOADED, THE MAGAZINE IS REMOVED, THE SAFETY IS IN THE "ON SAFE"

POSITION AND IT IS POINTED IN A SAFE DIRECTION.

We highly recommend that your rifle be cleaned with the BOSS

installed on your barrel. On the A-Bolt, remove the bolt and clean rifle

from the breech end. The BAR, by design, must be cleaned from the

muzzle end. Use extra care when cleaning to avoid damaging the

muzzle crown.

Modern cartridge jackets are made mainly of copper and zinc. These

metals glide easily and prolong barrel life; however, residues from

copper and zinc stick to the barrel and require more frequent

cleaning. As top benchrest shooters have known for decades, copper

solvent is the key to cleaning a barrel for optimum accuracy. The

recommended cleaning procedure is as follows:

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 the bore with a good copper solvent using the manufacturer’s

recommended procedures. After neutralizing the solvent, generally

with oil, it is important to swab the bore dry to 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 MANUFACTURER’S

RECOMMENDATIONS EXACTLY.

3 If necessary, the BOSS® may be removed to facilitate cleaning

your rifle.
