I bought a Bore Snake at a gun show for his Ruger 10/22. The .22 Bore Snake sells for around $15.00 - $17.00. Dennis reported that the first time that he used his Bore Snake it made his Ruger's barrel look brand new. They are also available at Academy, Wal-Mart, and Sportsmen's Warehouse. Product information is as follows:
The Bore Snake™ - The world's fastest gun bore cleaner®
Simply a better way to clean handguns, rifles, and shotguns.
Brushes and swabs the bore in one quick pass.
Has built-in bore brushes.
No assembly required.
Lightweight and compact.
Solvent compatible.
Washable and reusable.
No exposed metal to damage sensitive rifling or crown.
Multiple short brushes embedded in the floss pass easily through the shortest action or port. The initial floss area (inside the barrel) removes loose grit and debris prior to the scrubbing action of the brush. The main floss, with 160 times more floss than a patch, super cleans the bore. The brass weighted drop-through cord slips easily down any barrel. Simply grasp and pull the cleaning cord through the barrel. One pull through does it all.
