Overview

This 22 caliber rimfire jag is designed for shooters who want a more reliable patch fit when checking and cleaning a bore. Bore Tech describes it as a heavy-duty alloy jag with a protective coating intended to stand up to harsh chemicals while remaining barrel safe. Its precision-machined construction is meant to provide consistent, concentric pressure on the barrel surface, which can help reduce wasted patches and cleaning chemicals during routine maintenance. It is a practical choice for careful rimfire cleaning where a proper seal matters.

Considerations & Trade-offs

  • Designed specifically for .22 caliber rimfire use, so it is not a universal jag for larger centerfire or shotgun cleaning needs.
  • The product is positioned as a brass-free alternative, which means users accustomed to traditional brass jags may need to adjust their cleaning routine and patch fit expectations.
  • Its benefits are tied to proper use with Bore Tech cleaning products and patches; results may vary if paired with other systems or accessories.
  • This is a specialized cleaning accessory rather than a multi-purpose tool, so it adds value mainly for shooters who want a dedicated bore-cleaning setup.
