Aero Precision are the best value going and very lightweight. .
Aero mounts are fine for a general use rifle, but not on a precision rifle, IMO.
Bobro, AD, Spuhr, Geiselle are serious mounts for serious rifles; no experience with LaRue.
Leupold, Burris, Warne & Vortex seem to work for the most part too, for less money than the high end stuff.
