UTG Picatinny Trijicon RMR Mount, Lower 1/3 Co-witness

• Lower 1/3 co-witness height: The mount positions an RMR-pattern optic at the right height to keep standard AR iron sights visible in the lower part of the window, giving a familiar sight picture without crowding the dot.
• 6061-T6 aluminum construction: A CNC-machined aluminum body keeps weight low while providing the rigidity needed for consistent optic alignment and dependable zero retention on a Picatinny rail.
• Integral recoil stops and Torx locking system: Square recoil stops and side-plate Torx screws help the mount stay planted under recoil, reducing the chance of shift after repeated firing or hard handling.
• Super slim, lightened profile: Material relief cuts reduce bulk and weight, which helps preserve the compact handling that makes a red dot setup fast and practical on carbines and rifles.
• RMR-pattern compatibility with included hardware: The mount fits the Trijicon RMR mounting standard and ships with mounting screws and tools, simplifying installation and helping the optic interface correctly from the start.

About the UTG Mounts Series

UTG Mounts covers a broad range of optic mounting solutions for modern sporting rifles and precision setups, with the family including dedicated mounts, scope rings, and cantilever designs for common tube sizes and optic footprints. Within this range, the Accu-Sync family represents UTG’s more refined approach to alignment, fit, and repeatable attachment on Picatinny platforms. The series is built around practical needs: keeping optics at the correct height, maintaining rail engagement under recoil, and offering configurations that match different shooting positions and firearm layouts.

Across the series, the design philosophy is straightforward: secure mechanical fit, sensible height options, and low unnecessary bulk. Depending on the model, the line includes quick-release variants, fixed mounts, and dedicated footprints for compact red dots as well as traditional scope rings in multiple heights. That makes the series relevant to users building lightweight carbines, hunting rifles, or tactical optics setups where correct optic placement matters as much as the optic itself. In practice, UTG Mounts are aimed at shooters who want a dependable interface between optic and firearm, with models tailored to common co-witness heights, offsets, and rail standards.

About the UTG Picatinny Trijicon RMR Mount, Lower 1/3 Co-witness

The UTG Picatinny Trijicon RMR Mount, Lower 1/3 Co-witness is a fixed red dot mount built for shooters who want an RMR-footprint optic on a Picatinny rail at a height that works naturally with standard AR-pattern iron sights. Its defining feature is the 30.73 mm overall height with a lower 1/3 co-witness geometry, which keeps the iron sights available as a backup reference while leaving the optic window less obstructed than an absolute co-witness setup. For fast target acquisition on a carbine, that usually means a cleaner view of the dot and less visual clutter during rapid strings.

The mount body is machined from aluminium and uses a slim profile with lightening cuts to keep the setup compact. That matters on a rifle intended for quick handling, where excess bulk around the receiver can make the optic feel more intrusive than necessary. UTG also uses Torx locking screws and square integral recoil stops to improve rail engagement and help the mount hold zero through repeated recoil and routine transport. The 0 MOA configuration keeps the optic level to the bore, which is exactly what most shooters want from a compact reflex sight mount rather than a long-range scope base. Because it follows the Trijicon RMR mounting standard, it suits not only RMR-pattern optics but also other compatible red dots that share the same footprint, making it a practical choice for AR builds and other Picatinny-equipped platforms.

About UTG

UTG is the product brand of Leapers, Inc., a company founded in Michigan in 1992 and headquartered in Livonia, Michigan, United States. Leapers developed its business around optics and shooting accessories for hunting and shooting sports, and its catalog has grown to include riflescopes, mounts, rings, bipods, and related support equipment. The company’s first product was a compact 4×28 scope, which reflects its long-standing focus on practical field and range optics.

Over time, Leapers expanded beyond basic accessories into broader optics and mounting systems, including the UTG PRO line introduced in 2009 and a dedicated optics research and manufacturing center in Taiwan established in 2018. That background is relevant here because mounts are a core part of the company’s offering, and UTG has built a strong reputation for producing functional, application-specific mounting solutions for common sporting and tactical platforms.
