Overview

Designed for routine bore maintenance after shooting high-velocity, jacketed bullets, this cleaner is intended to break down and remove copper fouling without using ammonia. Its binding agent helps keep dissolved copper from settling back into the bore, supporting a more complete cleaning process. The formula is described as environmentally safe, biodegradable, odorless, petroleum free, and non-hazardous, with use on steel, stainless steel, and lined barrels. It also offers a rust-preventative benefit and is available in a 16 fl. oz. bottle for extended cleaning sessions.

Considerations & Trade-offs

  • Designed specifically for copper fouling, so it addresses a narrower cleaning task rather than serving as a general-purpose bore cleaner.
  • The formula is described as safe for steel, stainless steel, and lined barrels, but no compatibility is stated for every barrel or firearm component.
  • Its conditioning and rust-preventative effects are presented as repeated-use benefits, so results may depend on regular application rather than a one-time treatment.
  • Available in a 16 fl. oz. bottle, which is practical for frequent cleaning but may be more product than occasional users need.
