The Talley Mossberg Shotgun RMR Mount Black is a scope mount built to fit the Mossberg shotgun receiver (manufacturer part number RMRMSS).

It provides a direct-mount footprint for a micro red dot such as the Trijicon RMR, replacing the rear iron sight or top rail section it’s machined to fit.

Key Specifications

• Designed as a direct-fit solution rather than a universal/adjustable mount, for a precise, repeatable return to zero.

Frequently Asked Questions

Will this fit my rifle?

This scope mount is built specifically for the Mossberg shotgun receiver. Confirm your receiver matches that action/model before ordering, since scope mounting hardware is not interchangeable across unrelated actions.

Do I need gunsmithing tools to install this?

Installation uses standard hand tools (a torque wrench or hex driver is recommended); no drilling or gunsmith fitting is required for the Mossberg shotgun receiver interface.

Does this come with mounting hardware?

Yes, the mounting screws needed to attach it to a compatible receiver or rail are included.
