it would have to be a special machined part which for me is something I don't do. I don't have the CNC equipment or the time to screw around with making my own cylinders so I've used a couple different types and I'd have to say I like the Bowen design the best but it's not recessed it's just a standard cylinder. I figure if it's good enough for the most elite gun builder in the country it will work for me.

I won't be wronged. I won't be insulted. I won't be laid a-hand on. I don't do these things to other people, and I require the same from them. John Wayne-The Shootist
