I received a set of Titanium 34mm Murphy rings in black a few months back, I haven't mounted them yet though. They are going on a wierd tactical/lightweight/long range laser/coyote rig that I am still waiting on parts for.
Fit and finish look great and to describe them as ultralight would be a gross understatement, when they showed up, I thought they sent me an empty box!
Oh and by the way, I believe I ordered them on a Thursday and they showed up the following Monday, wow.
