My 204s are beginning to see a lot more action in the rat fields than the 223s. Last year the accuracy in one 204 was falling off drastically so I was already making plans to replace the barrel when I got home.
Luckily I scoped the bore and found a carbon build up so thick, It took several days to get it all out. Now it's back to shooting those half inch groups that we all love to see.

I could wish a lot of things on my worst enemy but neuropathy ain't one of them.
