Its unique formula allows for indefinite soaking, includes rust protection, and is trusted by top shooters to restore and maintain firearm accuracy. ## Description Bore Tech proof-positive bore Stix are quite simply the finest coated cleaning rods available, period! Review: Great and not smelly - Prefer this over the ammonia based solvents! Works great and gets the same result as the smelly ammonia based copper solvents. Review: Works quickly on less fouled barrel bores as well as deeply fouled barrels. - Bore Tech Cu+2 Copper, 4 oz seems to be a quality chemical for helping remove copper build up from rifle bores. I have used it in conjunction with other Bore Tech products and find it does a remarkable job of removing copper, as do the Carbon removal product and the all-around product for removing the carbon and both copper and carbon. Just follow the directions and repeat them as necessary and you will enjoy rifle bores that can be as accurate as possible because of removing built up fouling from the bores. I cleaned up the bore of a Winchester 67 22 that had sat neglected for almost twenty with nothing but a regular cleaning instead of a deep cleaning as provided by the Bore Tech products. Now there is hardly any fouling left in the barrel, and I am anxious to shoot the rifle again to see if the accuracy has indeed improved. A 90-year-old rifle could be a shooter as good as it was in 1934-1937, hopefully. This product should not be used for deep cleaning after every visit to the range, but only if accuracy begins to degrade after much shooting. ## Features - Rapidly oxidizes and breaks down Copper tainting by reconfiguring its electronic state - 100% ammonia and barrel Impervious - Will not etch or harm barrel steels and can be Imperviously left to soak in the bore for an Infinite period of time - Also contains a short term rust stopative, which shields and conditions the firearm's bore after Cleaning - Copper that surpasses the rigorous demands of today's top Shooters and cleans Copper tainting faster than traditional petro-ammonia based solvents ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0070IRZFI | | Best Sellers Rank | #21,738 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #8 in Gun Solvents | | Brand Name | Bore Tech | | Customer Reviews | 4.8 4.8 out of 5 stars (450) | | Global Trade Identification Number | 00667739980036 | | Included Components | Cu+2 Copper Remover | | Item Type Name | Cu+2 Copper Remover | | Item Weight | 0.25 Pounds | | Liquid Volume | 4 Fluid Ounces | | Manufacturer | PROOK | | UPC | 667739980036 | ## Product Details - **Brand:** Bore Tech - **Included Components:** Cu+2 Copper Remover - **Liquid Volume:** 4 Fluid Ounces - **Manufacturer:** PROOK - **UPC:** 667739980036 ## Images ![Bore Tech Cu+2 Copper, 4 oz - Image 1](https://m.media-amazon.com/images/I/61+9kUFJtdL.jpg) ## Questions & Answers **Q: What does "100% ammonia and barrel Impervious" mean? Does that mean this is 100% ammonia and won't hurt your barrel? Or won't react with ammonia?** A: It doesn't contain ammonia and it works very well. Highly recommend. **Q: How’s the smell? can you describe the smell? i can’t stand hoppe’s 9 bore cleaning. thanks** A: Too subjective to describe the smell. Your best bet is to try to find someone who uses it and see for yourself before you buy some. I will say that it doesn’t have a strong ammonia smell like some I have used. It is an excellent product and works extremely well. I understand the adverse reaction to certain smells. My daughters had a huge collection of Strawberry Shortcake dolls in the 1980’s and to this day anything with a blueberry sent makes me gag. I used to like blueberries before that. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great and not smelly *by C***M on November 17, 2025* Prefer this over the ammonia based solvents!
