Bore Tech C4 Carbon Remover, 4 oz

Outstanding. Cleaned stubborn carbon rings around the chambers right off, just let it soak for 15min and then go with bronze brush.

Appears to be a quality product, as are the other Bore Tech products I have and do use. I use this product to remove stubborn carbon rings in my rimfire rifles. One will fire short, long and long rifle ammunitions which produces different levels and locations of carbon rings and the C4 Carbon remover removes all rings no matter the location. It does not take long and only a little of the C4 that has a few minutes to sit on a damp swab to completely remove the rings. The oldest rifle I have had year of buildup in the chamber, and I was able to remove it rather easily from there using the C4 Carbon Remover. When I ordered the Bore Tech products, I initially intended to order the large size container but decided to get only the 4 oz. size as I was going to try a new product for me. It does such a good job so quickly the 4 oz. containers will last quite a while without degrading. I am now an old man but if any of these products run out for me, I will certainly order more.

This stuff works, absolutely incredible. I have struggled for years to rid off carbon on my guns and this did it without a sweat. Will will be purchasing more when I run out. Also love that there is no odor

I use this on carbon buildup on revolver cylinder faces and the forcing cone areas. It does good job at removing 99% using a large cleaning patch, the last little bit comes off with a light rub with some fine synthetic steel wool, no scratches. I found that if I soak a large patch with the C4 and let that sit on the carbonized area for a minute or two, the carbon comes off easier. The next test will be on an AR-15 bolt carrier group.

Does it remove carbon effectively? It does. Better than other brands I've tried? Yes. I'm happy with the results, but I'm not really happy with the price. If you have tough carbon to remove it's worth a try, but don't expect miracles.

This is a good product, but it is expensive.

This is a great product and it does exactly what it says and what I need it to do. It's a little pricey but I don't mind spending money on something that works and trust to take care of my equipment.

I've been using a premium CLP that's supposed to be great on carbon. I've also been using a brass tornado brush. My barrel looked shiny clean. NOPE. C4 immediately broke down the carbon I couldn't see. It looks and flows like water. This is best used at the sink. I let it soak and followed up with a nylon brush and the black just came out all over the bottom of the sink. After the 2nd patch ran through clean I took advantage of the sink. I used Dawn on the brush and washed the inside and outside of the barrel. Boy is it nice. C4 seems to leave behind a left over dried soap feeling. The wash down in the sink got rid of that feeling. I think this takes everything off down to the metal. Oil/CLP is a must to complete the job. I can't believe how easy this was!
