UTG Super Slim Picatinny RMR Mount Lower 1/3 Co-Witness Matte Black

The UTG Super Slim Picatinny RMR Mount is a precision optic mount designed to position RMR-footprint red dot sights at the correct height for a lower 1/3 co-witness with standard AR-15 iron sights. The slim, low-profile clamp tucks the optic close to the rail while still clearing the front sight post, keeping the overall sight picture compact.

The body is CNC machined from 6061-T6 aircraft grade aluminum and finished in a matte black anodize for corrosion resistance and long-term durability in the field. A 0.95" saddle height places the red dot window in the lower third of the sight picture when paired with standard-height backup iron sights, allowing the shooter to use the irons through the lower portion of the optic's window or run the dot alone.

Installation uses locking Torx screws paired with a square recoil lug that indexes against the Picatinny rail slots for a secure, repeatable mounting surface that resists side-to-side shift under recoil. The top clamp accepts Trijicon RMR and other optics built to the same RMR footprint, including many popular aftermarket red dots.
