This guide details how to install an Outer Impact Modular Red Dot Adapter (MRA) system on a Sig P320 pistol that is not originally optic-ready. The process involves removing the rear iron sight, cleaning the dovetail, installing a filler piece and mounting plate, and then attaching the red dot sight. This method allows for the addition of modern optics to older handgun models without requiring slide milling.

Quick Summary

The Outer Impact Modular Red Dot Adapter (MRA) system allows you to add a red dot sight to pistols not originally designed for optics. It utilizes the rear iron sight dovetail, replacing it with a mounting plate. This non-permanent solution requires removing the rear sight, cleaning the dovetail, and securing the adapter with screws, typically to 25 inch-pounds.

Frequently Asked Questions

How can I add a red dot sight to an older pistol that isn't optic-ready?

You can use an adapter system like the Outer Impact Modular Red Dot Adapter (MRA). This system replaces the rear iron sight dovetail with a mounting plate, allowing you to attach most red dot sights without permanent modifications to your slide.

What is the Outer Impact MRA system and how does it work?

The Outer Impact MRA is a universal system that uses the rear slide dovetail to mount red dot sights. It involves a filler piece and a mounting plate that create a secure compression fit, enabling optic installation on non-optic-ready handguns.

What are the main considerations when installing an MRA system?

Key considerations include ensuring the firearm is unloaded, thoroughly cleaning the dovetail, properly torquing the mounting screws (around 25 inch-pounds), and understanding that this method typically sacrifices the ability to co-witness iron sights.

What tools are needed to install an Outer Impact MRA adapter?

You'll need tools to remove the rear sight, such as a sight pusher or punch. A nylon hammer for gentle tapping, degreaser for cleaning, and a torque driver for precise screw tightening are also recommended for a successful installation.
