I'm trying to get rid of most of my kits that I don't have both cocker and Angel threaded backs for, so this ones up. Nice kit, I like the fact that it includes a 10" tip. Cocker threaded. One of the backs is scratched up where it got stuck in an old marker and I had to use a vice to unscrew it, and unfortunately the buffer slipped and the vice grabbed the bare barrel. You can just barely make out which one in this picture. Still a very useful kis as the bore sizes are: .680, .683, .686, .689 (the scratched one), .692, .695. $45 shipped continental US.
