I've never used an ADM mount but have a buddy who likes em well enough. I've heard the argument on the "special tool" (a 3/8" wrench) used to adjust the LaRues but I simply look at it like this; It's a one time fit and the wrench comes with the mount just like the Torx wrench you use while mounting the scope. I keep a wrench in my bag if I ever need to use it but in the past several years of using them, I've never needed it.

We have lot's of options and that's a good thing. I remember when it was Armalite and A.R.M.S. oh and B-Square.
