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.
You're not alone in that you don't make your own cylinders. Even John Linebaugh in the past has commisioned that part out -- don't know what he is doing nowadays, but many gun builders don't make their own cylinders. For a very long time, only a couple have made their own and they have made them for other gun builders.
