Pros

  • Fast-working cleaning gel for copper, carbon, and lead fouling in bores

Considerations & Trade-offs

  • Designed as a cleaning gel for bores, so it is more application-specific than an all-purpose gun care product.
  • The 4 fl. oz. net contents may be a modest amount for frequent or high-volume cleaning sessions.
  • Its rust-removal claim is limited to rust from bluing, so it should not be treated as a general rust-restoration solution.
  • Use requires a bore brush and manual application, which adds a step compared with spray-on cleaners.
