I have one that I would consider selling. I bought it a couple years ago and it had been used when I bought it. I've put less than 1000 rounds through it. I can email some photos in the next couple of days if you are interested.
I shoot with a guy that has been shooting a Butler for quite a few years now. He shoots it well, but has 2 of them so he can keep shooting. Have seen him go to his back up gun multiple times this year. He is a farmer, so he is very mechanically talented. Also, has Butler's phone number on speed dial to get parts coming. They are great guns when they are running. Hopefully the new ones are better.
