IronWorker378How does KG-12 work so well ?
KG-12 is the quickest and most effective of them all. How does it work ? All copper from other cleaners leave a deep Blue residue on patches and not all the copper has been removed. But KG-12 that gets it all and leaves a brown residue ?

Tyler KempWell the copper is brown without reacting to anything, so obviously it doesn't do that. Other than that...

Love shooting precision and long range. Big bores too!
Recent college grad, started a company called MK Machining where I'm developing a bullpup rifle chassis system.

IronWorker378I'm familiar with that test. So KG-12 bullet looks like the Copper has been etched away. So this stuff is some kind of Acid?

IronWorker378Jimmy you leave it the barrel no more then a few minutes. I use it. I've used most copper removers. This stuff gets it all out with 1 or maybe 2 applications. But first get the Carbon out with what ever you have.Then use this stuff its amazing.

I spoke to the owner of KG industries and he told me you can leave it in the bore over night, but in a couple of hours ther wontbe any copper left>

IronWorker378So the "How it works" mystery of KG-12 lives on? Is there any chemist out there that can enlighten us before Obama tax's us to death.
