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. (Notes: a red dot sight will not likely colocate with the ghost ring sight due to different sight heights .) The rugged side guard is designed to protect the sight from unexpected encounters.

Designed for use on Mossberg 500 and similiarly tapped and shaped receivers
Comes with mounting hardware and instructions for easy installation
CNC machined from 6061-T6 aluminum with hardcoat anodized finish

NOTE: For Mossberg 930 and 940, 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.

FAQ

I have a heavy barrel on my shotgun. Will this work with it?

Yes. The rear sight will fit perfectly. For the front sight order the HB or HB Snub sight.

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.

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.
