Barnes Bullets CR-10 Bore Cleaner 8 oz Squeeze Bottle

The Barnes Bullets CR-10 Bore Cleaner is a specially formulated copper solvent engineered to strip the toughest fouling from a firearm bore. Sold in an 8 oz squeeze bottle, CR-10 aggressively loosens and lifts stubborn copper, brass, and lead deposits along with residual powder fouling, leaving rifling clean for better accuracy and longer barrel life.

Built around a non-corrosive formula, CR-10 is safe for standard barrels and will not harm bore steel. It is a go-to choice for precision rifle barrel break-in as well as routine cleanup of any centerfire firearm where copper fouling is a concern. The squeeze bottle delivers controlled application, so a patch or brush can work the solvent through the bore and keep rifling sharp round after round.

Key features of the Barnes Bullets CR-10 include:

• Removes copper, brass, and lead fouling along with powder residue
• Non-corrosive formula that will not harm barrels
• 8 oz squeeze bottle for controlled application
• Ideal for precision rifle barrel break-in and ongoing copper-fouling maintenance
