This fully adjustable Ghost Ring rear sight with fiber optics is specifically designed for Mossberg's receiver. It lines up with the stock tapped receiver and doesn't interfere with the thumb safety.
The 5-inch long Picatinny rail is integrated with the sight, making it easy to mount a scope or red dot sight. (NOTE: Dot will not line up with the ghost ring sight.) The rugged side guard is designed to protect the sight from unexpected encounters.
NOTE: For Mossberg 930, the rear sight has a slightly different fit. We are working towards a new product to work well with this model, but please contact us if you have any questions.
I have a heavy barrel on my shotgun. Will this work with it?
Yes. The rear sight will but you will need the MX Front Band Clamp Sight – HVY which is not yet released. Sign up to be notified when it is available.
Will this work with the EX Front Sights?
No. The heights don’t line up. Use the MX Front Sights with the MX Rear Sight.
I have a different Mossberg model (not a 500)? Will the sight line up with the receiver holes and fit my shotgun’s profile?
Print out this CUT-OUT document (don’t scale it to fit page) and lay it on your receiver to see where the holes end up and how it curves to see if it fits your receiver.
