The Outer Impact Multi-Footprint Dovetail Optic Mount (MRA) for the Sig Sauer P365XL gives you a flexible way to run a red dot without committing to a permanent slide cut. It is designed for shooters who want to test different optics, avoid custom milling costs, or preserve resale value while still adding a reliable optic mounting solution to their pistol.
Precision-machined from billet 7075-T6 aluminium, the MRA is built to handle recoil and repeated use without adding unnecessary bulk. Outer Impact pairs the plate with steel alignment pins and T-10 Torx mounting hardware to help maintain alignment and zero, giving you a durable, multi-footprint platform for a wide range of popular pistol red dots.
