LaRue RMR Lower 1/3 Mount
The LaRue RMR Lower 1/3 Mount is a quick-detach mount engineered to position the Trijicon RMR at a lower 1/3 co-witness height on standard AR-15 flat-top receivers. A slight cantilever pushes the optic forward for improved eye position while maintaining a compact footprint.
Precision-machined from solid bar-stock aluminum and finished in a matte black anodize, the RMR Lower 1/3 Mount is built for durability, repeatability, and hard use. The LaRue Speed Lever QD system provides a secure lockup with a guaranteed return to zero, allowing the optic to be removed and reinstalled without shift.

RMR Lower 1/3 Mount
Not sure how many LT optic mounts I have now. I only use them because I know they will work. Wasn't sure I liked the looks of this one, but once on I think it looks pretty cool. Perfect co-witness and return to zero. If you want to mount an RMR, don't hesitate.

RMR Lower 1/3 Mount
Another awesome larue product. about an hour after placing my order I got notification of shipping. My last jar of Dillo dust was empty so every box from larue is like Christmas with all the extras. The RMR mount is perfect, it fits nice and snug and like every larue mount once it's on, you can beat it with a bat and it will hold strong. The mount does say lower 1/3 but it is absolute cowitness with my magpul BUIS. And that cantilever mount just looks good.

RMR Lower 1/3 Mount
Everything I expected. Small and to the point, my RMR fit perfectly. Flip up Magpul sights are dead center. Great product. LaRue is where any future mounts will come from for me. Period.
