I've got a 30" stainless benchmark barrel sendero contour it's threaded for a savage large shank action. It also has one of Jim See's medium size muscle brakes. All threading, chambering, and installing of brake was done by benchmark barrels.
It has exactly 109 rounds down the barrel, and it was properly broken in.
I'd like $575, dropped to $550, another drop $525, final drop $500 for barrel and brake. I've got $650 in it. I'll guarantee the round count if you want a smith to look at it.
