I've heard talk about the safety delete but never looked into it because both of my Marlins are pre safety. The saddle ring piece is new to me though and a great idea. I put one of Henry's saddle ring conversions on my 22mag. It rattled so bad I couldn't get it off of there fast enough but the one you posted appears to be allot better made.

My 1946 M39 and 1976 44M.
