My vote is for LaRue Tactical.
They offer several types of mounts depending on the type of optic you are interested in mounting.
In my case, I have an LT-104 SPR with VFZ mounts for my Trijicon AccuPoint 3-9x40 on a dedicated hunting rig in 6.8 SPC.
Plus, you get the neat extras in every shipment, like Dillo Dust and stickers!
