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
Allows Trijicon IR-Hunter to be mounted much further back, in proper position for eye-relief with7.62x51mm rifles with flat-top mounts. Very well built.

Worked on my trijicon ir hunter

ACOG RCO Mount
Love these mounts. Provides the ideal eye relief along with a QD locking lever. I'm also running a KRAM spacer to provide extra vertical height to clear my fixed irons and provide slightly better ergonomics. Works well especially if you're not running a piggy back rmr setup. Would definitely recommend.

ACOG RCO Mount
Literally the best addition I've added to my rifle. It put my ACOG right where I needed it. I wish I would have found this mount earlier. Worth every penny.

ACOG RCO Mount
Needed to move my Primary Arms 5x prism back to get proper eye relief on a flattop lr308. Mount was great, quick release interferes with the extended ambi charging handle so it limited my adjustability just a bit. Consider that when you are selecting your charging handle. Can’t say for sure if it would clear a stock CH or not. Overall though I was able to gain a full 1 1/2†which was the magic number. PA prism fit right on it like they were made for each other.

ACOG RCO Mount
Perfect for the Primary Arms SLx 3X Prism! I’m a sucker for eye relief, and this mount brings my PA Prism Scope more rearward on my AR receiver when mounting it. And it is aesthetically pleasing! 5 stars hands down!!

ACOG RCO Mount
The LT681 when used with two Primary Arms spacers (2 x 0.34 inch high each = 0.68-inch) and the SLx 3x Gen III (non-micro) prism optic achieves a 3.005-inch height over the bore axis at the tip of the chevron (with a Mil Spec 1913 rail height of 1.22-inch). Doing the math (3.005 - 1.22) give you 1.785-inch of the chevron tip above the 1913 rail height, which clears most objects mounted forward on the rail.

ACOG RCO Mount
Well, I doubt my review is needed but… this is the second one I’ve owned. As far as acog mounts go, this one is by far the very best. I mean, it’s so good I bought it. Seriously, think about that. The trijicon acog comes with a mount and it’s not like trijicon makes crap… no way in hell they would put a sub standard mount with the optic that put them on the map just out of fear someone would mistakenly think the acog wasn’t true BUT next to the Larue mount the trijcon mount is substandard. The precision on the Larue is twisted good. i’ve removed it and replaced it and it was perfectly zero’d. That’s crazy! Tactically the Larue is far superior because fast removal means fast access to BUIS. Not to mention no torque prceedure in putting it back on… and yes, every mount has a torque spec. The throw lever’s lock is genius and yeah… once you’ve seen one it becomes hard to live without… I’m not gonna cheap out after dropping over a grand on such a good optic on such a great rifle… that would be like having a dream hot rod with a high end super charger and driving it on generic touring tires.
