Primary Arms SLX FS Flip-to-Side Magnifier Mount 1.75 Inch, 2-Bolt Bottom Interface

Overview

The Primary Arms SLX FS Flip-to-Side Magnifier Mount is designed to pair a 2-bolt magnifier behind your favorite red dot or microprism, giving you a flexible path between magnified and unmagnified views. The center of the magnifier can be aligned to either Absolute or Lower One-Third cowitness, letting you tailor your sight picture to the moment and your preferred stance.

Built for real-world use, this mount balances quick access with dependable alignment. When you need magnification, the flip-to-side mechanism provides a smooth transition; when you don’t, you can tuck the magnifier out of the way without losing your zero or repeatable alignment.

Build, compatibility, and durability

Constructed from durable 6061-T6 aluminum, the mount offers a rigid platform designed to hold up under recoil and field conditions. A steel alloy crossbolt drives the mounting torque, rated up to 55 in-lbs, helping ensure a tight, secure fit even after repeated install and removal of magnifiers.
