Modular Red Dot Mount

Modular Red-Dot Mount for Sig Sauer P320-M17, M18, and X-5 Legion (Civilian Version)

OuterImpact is pleased to introduce the Modular Red-Dot Mount/Adapter (MRA) for the civilian versions of the Sig Sauer P320-M17, M18, and X-5 Legion. This product allows shooters to use a wide variety of red-dot sights on these models with just a single adapter. OuterImpact has placed great emphasis on ensuring that the fit and finish of this system are top-notch.

Advantages and Features

The growing popularity of mini red dots on pistol platforms offers many possibilities. However, not everyone wants to commission a custom-made slide cutout. 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 Sig Sauer P320-M17, M18, and X-5 Legion (civilian version) 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.
