Having had a Lyman 21 on an original 1895 Deluxe SO takedown rifle in 405 WCF,-I would advise NOT taking your
MY-21 off your rifle. Keep your 92 Lyman 21 D until you find the right sight. Check with Gary Fellers in Fort Worth.

Never be in a hurry to make a mistake...........I have a nice Lyman 21 on an original 1886 in 33 WCF.
