Remington / Winchester Base Heights

In order to determine the appropriate height base that you need, you will need to know the measurement from the center of the bore(at the muzzle) to the center of the front sight.

Now subtract .650 from the measurement that you just took. If necessary, round the result either up or down to the nearest even .025 increment (.742 would yield .750). Now you have Height X from the above drawing. This is the number that you should use to order your base from us.
