ACOG RCO Mount
The LaRue ACOG RCO Mount is a precision quick-detach mount designed to position Trijicon ACOG optics farther rearward for improved eye relief and ergonomics. Originally developed for the ACOG RCO, this mount is especially beneficial for users running fixed stocks or body armor, while remaining compatible with all full-size ACOG models.
The contoured rear profile allows unobstructed access to the charging handle, and LaRue’s patented Speed Lever QD system delivers repeatable return-to-zero when removing and reinstalling the optic. Machined from solid bar-stock aluminum and finished with a durable matte black anodizing, the Larue ACOG RCO Mount is built for duty use where reliability and precision matter.
Each mount ships complete with mounting hardware, adjustment tools, thread locker, and installation instructions.

ACOG RCO Mount
I like everything i've bought from LaRue top quality products great service. If there's a problem it's taken care of. There mounts are top quality & are always zeroed even when i've taken them of many times. i put them on primary arms budget scopes & i don't mind the price(buy once cry once) they're totally worth it in my opinion!

ACOG RCO Mount
I have nothing but good things to say about this mount. Precision machining, very secure mounting, allows optics to be placed further back without interfering with anything else on my rifle and an excellent price for the exceptional quality. My only complaint is the length of time it took to get it. Fortunately, I was not pressed for time, so I was able to wait for what I can only describe as perfection. Thank you for another quality product!

ACOG RCO Mount
I think the LT681 mount is a work of art as far as design and manufacture. It did exactly what I needed, which was to move my Burris AR336 rearward on the upper to solve what was for me an eye relief issue. I was afraid I'd wasted my money on an optic until I discovered the LR681. It's a great idea turned into a great product. A LaRue magnifier flip mount previously purchased is also top notch in quality and design. My experience is that I can count on LaRue products being of the highest quality. BTW the customer service was great - LaRue confirmed by telephone this mount would work with the AR336 and then sent regular email updates about the status of my order.
