Patch Info
Use this guide to find the right cleaning patch size for your firearm's caliber — fast, simple, and accurate.
Choosing the correct patch size is key to an effective clean. A patch that's too small won't scrub the bore properly; one that's too large can get stuck. Use the chart below as a starting reference, then always confirm with your manufacturer's specifications.
