Has anyone ever used KG 12 copper remover? I was just reading on a web site that did some test on different gun cleaning solivents. The KG 12 did the best of all for removing copper fouling and it has no ammonia in it at all that can cause pitting or ruine a stainless steel barrel.
I know about CR-10 and Sweets 7.62 but what about this KG 12 stuff. Any thoughts?
KG 12 Copper remover Ever used it?
