This is another great Lyman product. Fits into 3/8" rear slots very well. Keep in mind that this slot blank is probably intended for modern rifles, as Lyman original slot blanks were flat top, not curved. This would not appear appropriate on your vintage Winchester.Pros: Well finished, high qualityCons: Not original flat top variety for older guns

A well made product. However, be sure you are comfortable with patiently filing and fitting this into your gun's sight dovetail. With patience it will fit very well. If you rush the job it will either fit loosely, or you will damage it by hammering on it to get it to slide into place.Pros: Finished nicely. Quality lookCons: Requires quite a bit of fitting by filing, etc.

I ordered this product to replace the rear sight on a Ruger 10/22 it will not fit in the dovetail without some careful Machining and even after you get the dovetail to fit it does not sit flush with the barrel and will be raised above it the product seems to be of good quality but for the purpose I needed it it just won't work
