Overview

This bore cleaning jag is designed for hunters and shooters who want a more controlled patch fit during routine rifle maintenance. Its copper-free alloy construction is intended to be as gentle on the bore as brass, while also avoiding false blue indications of copper fouling on the patch. The patch is held tight at two points to increase contact area, and the reverse taper helps guide it into the bore more smoothly. It is offered in .17 caliber with 5-40 male threads and is made by Bore Tech.

Considerations & Trade-offs

  • Designed specifically for .17 caliber use, so it is not a universal jag for larger bores.
  • The proprietary copper-free alloy is described as gentle on the bore, but the listing does not provide material details beyond that.
  • Its reverse-taper self-guiding design may help alignment, though it still depends on proper patch sizing and threading compatibility.
  • Patch retention is concentrated in two points, which can improve contact area but may require a bit of setup to find the right patch fit.
