Overview
Designed for shooters who need a focused solution for copper fouling, this bore cleaner is intended for use after firing high-velocity, jacketed bullets in hunting and competition rifles. Its ammonia-free formula is described as fast-acting, with an added binding agent that helps lift dissolved copper and keep it from settling back into the bore. The product is also presented as biodegradable, odorless, petroleum free, and safe for steel, stainless steel, and lined barrels. Regular use is said to help condition the bore and provide a rust-preventive layer, making it a practical maintenance option for serious firearm care.

Considerations & Trade-offs
- Designed for copper fouling removal rather than general-purpose bore cleaning, so it’s a specialized maintenance product.
- The 4 oz. bottle is a compact size, which may be less convenient for frequent or high-volume cleaning sessions than the larger 16 oz. option.
- It is described as safe for steel, stainless steel, and lined barrels, but no broader material compatibility is stated.
- The formula is ammonia-free and odorless, which reduces harshness, but the product still requires normal bore-cleaning time and repeated use for conditioning benefits.
