Modular Red Dot Mount for Mossberg 500 Shotgun

OuterImpact is pleased to introduce the Modular Red Dot Mount/Adapter (MRA) for the Mossberg 500 shotgun. This product allows shooters to use a variety of red dot sights on the Mossberg with just a single adapter. OuterImpact has placed great emphasis on ensuring that the fit and finish of this system are top-notch.

Benefits and Features

With the rising popularity of mini red dots on firearm platforms, not all shooters want to have a custom modification performed. Reasons for this may include:

High cost of modifications

Impact on the firearm’s resale value

The ability to try out different red dots

The OuterImpact MRA for the Mossberg 500 shotgun solves all these problems. The adapter plate is precision-machined from 7075 aircraft-grade aluminum, making it extremely durable and lightweight. Thanks to Weaver T-10 Torx screws and steel alignment pins, everything remains stable and secure, ensuring that accuracy is not compromised.
