Pro-Shot Products 8-Ounce Copper Solvent IV

Never used this before. Great substitute for my Kg12. Eats the copper out fast, no horrible smell, and pretty economical compared to some other copper removers. Follow the instructions and it works great. Be sure to remove the carbon to expose the copper before using this. It'll work a lot faster. I like the slight foaming action to keep it in contact with the rifling at the top of the barrel. Other watery cleaners tend to run to the bottom of the barrel and don't remove the top copper deposits without extra applications. This one gets it out on the first pass. Don't forget dwell time when using it. Give it a chance to do its job.

This stuff is amazing, cleans, copper and fouling with ease. That’s all you need to know.

it works and do you really want to spend $$$$ to get your barrel only microscopically better? It obviously cleans out brass fouling.

works as designed, fast shipping

Not a harsh copper solvent but does pretty well. Low odor.

just to let you know the cap is not all the way on.. you will loose about an half an ounce in shipping. have not used it yet.

Soak your barrel. Scrub it and then use clean patches. You will be surprised at the copper fouling you get from a supposedly “clean” barrel.

Recently I purchased a used gun. When I got it home I discovered that the barrel was dirty, so I ran a few patches through it. The barrel`s dust and dirt came out, but then I noticed what looked like rust, in the grooves of the rifle-ings. After doing some research I learned that it was copper fouling. Doing more research I came across this product, Pro Shot Copper Solvent IV. Good reviews, easy and safe in my barrel, low smell, and good price. So, I purchased this and a nylon bore brush. I started by running a dry patch. Then followed with a patch soaked with Pro Shot Copper Solvent IV. I let it set for 10 minutes, then scrubbed the barrel with the nylon brush, also soaked with the Pro Shot Solvent IV. Let it set for a couple minutes, then ran a few dry patches. My barrel was so filled with copper fouling that it took three repeats of this process to see no more copper and have clean patches. I then quickly cleaned my barrel with my regular products. Finished with a lightly oiled patch. Very happy with the results. I feel like I have a new rifle.

worked well for my trip, made it very successful

This is the copper remover to get! Ive tried all kinds, but none have worked as good as this. The smell is also not as bad as other's. Great stuff!

I must say, I was more than impressed. Over the years tried many products but this one is the best, I’ve used so far.

Does exactly what it’s supposed to do.

Once of the best solvents I have ever bought. After using it, I ordered another bottle.
