remington 521T rear sight mount-wanted

[swifty]

I am looking for a mount for a remington 521T that mounts a lyman rear receiver sight or a redfield rear signt. any information would be of help. I have a 521 T someone attached a scope and I would like to return it to its orginal set up.
Many thanks.

Check page 325 of the Brownells catalog number 57.   Top of the second column from the right under 'Target Foolproof' you will find the adaptors to allow a Lyman Universal Model MJT 90 to your 521T.  The sight itself is found on the facing page.  These and the 57 variant are often seen on internet auction sights such as Ebay in used condiition for considerably less.
