Midwest QD Optic Mount for Trijicon RMR Lower 1/3

The Midwest QD Optic Mount for Trijicon RMR Lower 1/3 is a quick-detach mounting solution engineered for operators who demand reliability and zero retention. Built by Midwest Industries, a trusted name in tactical rail systems, this mount interfaces with the Trijicon RMR reflex sight and positions it in the lower third cowitness configuration—a proven setup for duty and precision carbines. Law enforcement and military personnel rely on QD mounts to transition optics between weapons systems while maintaining zero integrity, making this an essential component for any professional or serious sporting rifle platform.

At the heart of this mount is Midwest Industries' industry-leading quick-detach lever mechanism, recognized for the smoothest operational feel on the market. The clamping system applies consistent pressure without damaging or "coining" Picatinny rail surfaces—a critical feature that preserves your firearm's integrity during repeated mounting cycles. A multi-faceted adjustment nut allows operators to dial in exact tension, accommodating different rail profiles and user preferences without requiring tools. The lower 1/3 mount height establishes a proper sight picture alignment with iron backup sights while keeping the optic within the optimal head position window.

This mount excels in patrol carbine setups, duty rifles, and AR-15 platforms equipped with Picatinny rails and Trijicon RMR red dots. Installation is straightforward—secure the mount to your receiver or handguard rail, then slip the RMR into the quick-detach interface until it locks positively. Weighing just 0.23 pounds, it adds negligible mass while significantly enhancing weapon modularity. Whether you're managing multiple rifle platforms or simply ensuring redundancy in a critical system, the Midwest QD Optic Mount delivers the repeatable precision and durability professionals expect.
