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.

Typical LaRue! Quality cannot be beaten! Customer service cannot be beaten. I only have LaRue mounts on my weapons. Keep up the great work! Outstanding from A to Z.

ACOG RCO Mount
Received the mount very quickly. Nice quality. Haven't gone shooting yet to prove its return too zero after dismount an remount but i believe it will work well. Had one small problem, the 5mm screws sent with mount were out of spec. about .005" small on there diameter. I work in a sheet metal/machine shop so got a couple of button top 5mm screws an ground them to the right length. Over all love the look and mounted perfect to bring scope closer to eye. 2 thumbs up LARUE !!!

ACOG RCO Mount
I purchased the LaRue Tactical ACOG RCO Mount, LT681 for use with my Primary Arms SLx 3x32mm Gen III Prism Scope. Works great - solid mount with solid quick release. Very satisfied.

ACOG RCO Mount
I bought this for my Burris AR536 and it fit perfect. Solid, high quality product just like everything LaRue makes. Does everything other reviewers say it does for their ACOGs and it works for the Burris AR scopes too.

ACOG RCO Mount
All my rifles have a LaRue mount. What I like they're top Quality, you can take them off & they always keep Zero. My scopes are Primary Arms & I prefer the LaRue even though my scopes are considered on the budget end. I think LaRue are well worth the price.

ACOG RCO Mount
I can confirm what others have said that this is an excellent replacement for the stock mount on a Burris AR-536. It brings the eye-relief into a very comfortable range from it's previously slightly uncomfortable range. I would highly recommend this to any owner of the Burris AR-536. You wouldn't think it, but it makes a world of difference.

Expensive and the wait was very long, but this mount solved every problem I had with my ACOG.

Typical top quality Larue! The RCO fixes the what I found to be a problem with Larue's LT100 mount. I ran an LT 100 for years on my AR15 SPR. As an assistant team leader and lead scout sniper for the local county Sheriff's departments E.R.T. I put the LT100 on backwards ( so the locking levers were on the right side. I like the left side of my AR platforms as slick as possible so nothing gets in the way of the charging handle and the right side of my bolt actions as slick as possible so nothing gets in the way of the bolt.)
