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
With an RMR09 it weighs a scant 3.65oz making it the lightest red dot with riser I own. I use it on an high end lightweight AR22 build and its awesome. Its the perfect height to co-witness iron sights and also to use with a PVS14 in an Aimpoint 1/4 turn mount. Like all my LaRue stuff, its perfect. Super strong, quick on/off, and a discrete matte finish.

RMR Lower 1/3 Mount
Mounted a Trijicon SRO on a 300blk SBR. As usual with Larue, it is perfect. Height is exactly right & solid as a rock. Return to zero after remove & reattach is more precise than the rifle is capable of.

RMR Lower 1/3 Mount
LaRue is definitely a 5 Dillo product! Rock solid attachment. Easy adjustment. Easy on. Easy off. Easy on. Return to zero every time. The mount comes with all the hardware and tools needed, so very quick to go from package to rifle/pistol.

RMR Lower 1/3 Mount
Outstanding craftsmanship. The RMR is tightly held in the mount. The QD lever makes the mount easy on/easy off.

RMR Lower 1/3 Mount
I own 3 mounts and cant say, but only great things. Sure it stings a little on the spend and you tell yourself I could have gotten a cheaper one and then you mount it and everything changes! It was totally worth it. From acogs to rmrs Larue is the shit for all your needs.
