Otis Bore Guide Kit Features The Otis Technology Bore Guide Kit aids in aligning a cleaning rod with the barrel of a firearm which helps prevent the bowing and bending that can damage the bore over repeated cleanings. This alignment protects the chamber and bore from accidental rod contact keeping the firearm s accuracy potential intact over its service life. A built-in solvent port reduces the chance of spilling solvent during cleaning which could otherwise ruin the finish of the firearm. The thumbscrew collar lock holds the guide firmly in place throughout the cleaning process. The kit includes a collar designed specifically for MSR and AR-style rifles creating a tighter fit and additional support for the upper receiver while cleaning. This universal fit also covers most centerfire and bolt-action rifles making the Bore Guide Kit a versatile addition to any cleaning kit. By keeping the rod centered and the solvent contained the kit turns a routine cleaning session into a safer more controlled process. For shooters who want to protect their barrel and finish during every cleaning the Otis Technology Bore Guide Kit is a practical universal solution.
