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
This is my first LaRue mount. Great fit for my SBR and it won't be my last product from them. I have seen one of the custom AR's that were done for the Texas Rangers and it is a quality rifle. Keep up the great work!

RMR Lower 1/3 Mount
HMMM.... what to do with this nice RMR I purchased???? I got the RMR to mount 45 offset on a scoped gun. I had it there for a little while and then for some reason it lost its luster after getting hung up on a few things and then sat in my safe for months thereafter... upon realizing I have such a nice optic going to waist I decided to check out what kind of mounts LaRue made and see if I can revive the passion for it. Enter LT827! I now have a whole new dilemma... how many guns do I want to run with just a RMR now... Oh wait that's right its a LaRue... I can run as many optics on my guns as I want :) LaRue's quality is unmatched followed up by one of the best warranties on the planet! Thanks for putting out such great Products!

As always fit and finish are perfect. RMR co-witnesses the iron sights and the lines make the whole set up streamlined. Fast both eyes open target shooting. Also very light weight makes the RMR a good choice for a light weight SBR. LaRue has offered another good option.

RMR Lower 1/3 Mount
This mount takes the RMR to its full potential. Its quality is nothing less than the very best, which is to be expected from LaRue. I used this mount to secure my RMR to my Stag 1L; I'm so glad someone told me about these before I just bought the standard Trijicon mount. It nicely placed the aiming triangle just above the fixed front sight post, and I found the front sight to be completely unobtrusive while shooting. I played with the mount, using the quick release lever to remove and remount it from my weapon multiple times; the zero held rock solid every time. I have never been able to engage targets more quickly; after playing with setups for years this is the fastest by far. If you're planning to put an RMR on your carbine this mount is truly the best of the best. And as for the fact that LaRue adamantly supports our second amendment rights...well that's not so bad either!

RMR Lower 1/3 Mount
I just put together a "pistol" with the Sig Arms brace and a 7.5" barrel with muzzle brake for a CQB and trunk gun. I had a Trijicon RMR on a pistol that I had stopped using. I put it on with a mount that I bought and a picatinny riser. Then LT came out with this and it is perfect for this "pistol". Its small, lightweight and looks cool. And the best part is that I didn't even have to re-sight it. Its perfectly manufactured and fitted.

Have not fielded it yet but don't have to. It appears to be up to LaRue standards.
