These Jags are studied to fit all firearms calibers. Once fitted in the bore, the jag provide a concentric pressure that helps the removal of fouling along the whole barrel. Made in aeronautical aluminium to prevent the release of copper residues on the patch, the jag firmly holds the patch for efficient swabbing during the cleaning process. These jags are specifically studied for this patch that has one unique size for all calibers from .22 to .50.
Conversely, several patches available in the market have different sizes depending on the firearm caliber.
