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
This fixed the eye relief issue I was having with my ACOG. I am able to move the scope to the very back of the upper receiver, and I can maintain a natural cheek weld with the stock and get the correct eye relief. The fact that it is quick-disconnect is just an added bonus! I absolutely recommend this for anyone with a 4x32 ACOG and a flat-top receiver. A much needed upgrade over the stock Trijicon rail mount.

ACOG RCO Mount
I have been around the block a couple times in my life and learned early on -YOU GET WHAT YOU PAY FOR. I have heard people bitch about how much these mounts cost yet think nothing at all dropping $3 to $5 at the coffe shop for a cup of java. I have a LT 681 QD mount holding my Trijicon ACOG on my Colt AR. Neither scope nor mount was cheap BUT my AR is the first thing I reach for when things go bump in the night . I don't lose any sleep worrying whether my scope will be out of alignment-even if I were to drop my rifle. I literally trust this combination with my life. How many other mounts can you honestly say that about? You can buy cheaper, but why?

ACOG RCO Mount
Ordered this for my Trijicon IR-Hunter 60mm. Pleased to say this mount works with no modifications. It allowed me to move the optic closer to get the perfect eye relief! It should have came with this mount from the beginning.

ACOG RCO Mount
I have used this mount for 4 years now switching out the ACOG TCO with a carry handle for competitions. The ACOG has consistently returned to zero every time. Thanks for such a great product!

This mount is a tank of all tanks. Solid construction and lock up. Very light and pleasing to the eye. You just can’t go wrong with LaRue mounts. Just stop reading reviews and hit the “add to cart†button. You will not be disappointed. This is the kind of mount that will surpass your lifetime and be given to yours spoiled grandkids.
