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...
I have a 930 JM Pro. I want to mount a red dot reflex sight * on it. The mounting rail allows the sight to be mounted several places along the receiver.
Is it better to mount it closer to the eye or further away?
* Vortex Venom red dot
Thank you.
