I have the Nikon M223 1x4 and the P223 3x scopes. Both very good scopes IMO. When I bought the P223 it was when Nikon was giving away the P-Series mounts for free when you purchased the scope. Main reason I bought it, just a great deal with the free mount. I doubt I ever mount it for use, dang impulse buys! :(
I bought the M-223 scope mount outright. Both mounts are very nice as well.
I am not crazy about the fixed 3x magnification, I prefer the variable 1x4 scope myself. It's a personal thing more than anything else, my eyes just do better with the 1x4 (set at 1x) for anything up close. I have mounted but never shot with the P223.
