    Does anyone know if the Williams "Ace in the Hole" rail with rear sight will fit on a Mossberg 930JM receiver. The rail is made for the mdel 500. Some people told me a standard straight 500 rail will fit on the 930, but the Williams Ace in the Hole looks like the rear part of the rail is turned down to match the countour of the rear of the 500 receiver. Is the countour of the 930 receiver the same as the 500?

    As I understand the 500 and the 930 have the same spacing for the tapped receiver. What I cannot answer is if they are in the same position relative to the contour on the receiver. I would guess yes but cannot say for sure.

    Best thing to do is call Williams directly and ask. The people there are very helpfull.

    I will add that the front holes on the 930 are shallower and you will need shorter screws to prevent them from rubbing on the bolt.
