Amazing Product 5 of 5 stars

Fired 200 rounds of winchester white box through a a new pistol today. Did the usual bore cleaning solutions and thought that I had the barrel clean. I followed up with Bore Tech C4 Carbon renover, per the directions on the bottle, I was shocked and amazed at the carbon filled patches that followed. I think that I need to reclean all of my firearms to see how much carbon the old cleaners had been leaving in the barrel.

Best cleaning product! 5 of 5 stars

Decided to give this product a try to remove some thick caked on carbon on my AR15 bolt. I didn't think anything would take it off. Actually tried using the Eliminator first, that removed some of the built up carbon with marginal results. Decided to try this Carbon Remover...WOW I am really impressed. Soaked it over night and besides pulling it out of the soak to lightly brush it with a nylon brush I really didn't have to use any elbow grease, this product did all the work.
