LaRue mounts were designed for carbine optics and accessories like Aimpoints and lights. They have created a usable riflescope mount, but much like all LaRue mounts, they chew up the rail/base. When you repeatedly remove and replace, you can cause damage to the rail/base, and you will have issues with wear on the rail that can affect return-to-zero (RTZ). I like my LaRue mounts for my Aimpoints, but the levers loosen up over time and I have to tighten them regularly. I've had a rifle lose zero due to loosening LaRue lever. I've never had an ADM lever loosen, because their design prohibits it. For a precision shooting, you don't want any possibility of shift.
John McQuay over at 8541 Tactical did a RTZ test with LaRue mounts, as well as with ADM and Bobro. The LaRue had zero shift. The other two didn't.
There is a pretty significant discussion over this issue over on SnipersHide, and one of the many things highlighted was that the LaRue mounts have among the smallest amount of engagement surface on the rail of all competing mounts. One LaRue lever has about 0.5" of engagement surface. One ADM lever has just a hair over 1.25" of engagement surface. A LaRue riflescope mount will then have around 1" of engagement on the lever side, while the ADM will have just over 2.5" of engagment surface. A SPUHR mount has engagement surface along the entire length of the mount.
SPUHR, GDI and Alamo Four Star are regarded as the strongest options on the market with the most engagement surface and best RTZ. Bobro and ADM are also highly regarded.
I realize that LaRue is a highly regarded product, but I am not sold on their scope mounts versus the competition. Add to that the fact that LaRue ditched their LE pricing, and I'm not really inclined to buy any more of their products since ADM offers exceptional products at better prices.
