Assembly RMR^® Picatinny Q-LOC 1/3 Co-Witness Trijicon^®

The Trijicon AC32075 RMR Picatinny Q-LOC Lower 1/3 Co-Witness mount provides a robust and precise interface for RMR- and SRO-pattern red dot sights. Its quick-detach Q-LOC lever ensures a secure lock on the Picatinny rail while maintaining the correct optic height for a clean co-witness with backup iron sights.

Lower 1/3 Co-Witness for an Unobstructed Sight Picture

The mount positions the red dot so that backup iron sights appear in the lower third of the optic window. This allows a clear, uncluttered sight picture while retaining immediate access to BUIS if needed. An optimal solution for shooters who demand speed without sacrificing redundancy.

Q-LOC Quick-Detach System

The Trijicon Q-LOC system uses a precision locking lever to secure the mount without tools. The clamp engages firmly with consistent pressure, maintaining zero even under repeated recoil. Optics can be removed in seconds for transport or maintenance and reattached with reliable return-to-zero performance.

Low-Profile, Stable Mounting

Sitting close to the Picatinny rail, the mount keeps the optic at an ideal height for fast target acquisition and a natural sight alignment. The stable platform ensures minimal shift during rapid transitions or dynamic shooting.

Durable Construction with Non-Reflective Finish

CNC-machined from high-strength aluminum and finished with a matte hard-anodized coating, the mount resists wear, corrosion and unwanted reflections. The non-glare finish prevents light signature and maintains visual clarity in bright or indoor environments.

Trijicon Manufacturing Quality

Produced on the same manufacturing lines as Trijicon’s optics, the mount offers precise tolerances, secure engagement and long service life. Compatible with all red dots using the RMR footprint and designed for any standard Picatinny rail, it provides a simple, dependable mounting solution.
