Really only two basic choices for rear sights among current production sights:
1. The Williams Target Foolproof, low or high; and
2. The Lyman 90 MJT.
The Williams Target Foolproof High or the Lyman 90 MJT will work better with a globe sight mounted on a screw-in base. Contact Steve Earle products for a front sight base.
The Williams Target Foolproof Low will work with the oem Remington ramp sight.
Least expensive would be a Williams low rear from the CMP estore and an oem ramp sight from Numrich (e-gunparts).
Play your cards right and the shipping from Numrich will be free. :bthumb:
