I have quite a few Larue QD mounts and I've been happy with them. A big question on mount selection is how you shoot. I shoot nose to charging handle (NTCH). The Vortex has ~4" of eye relief and with a NTCH shooting position I would recommend an extended mount such as the Larue SPR-E, ADM Recon-X or Bobro extended mount. Of the three designs I believe the Bobro is the best. I like my Larue's, but Andrew did a great job on the Bobro QD system.
FWIW, the Vortex QD mounts and the Noveske QD mounts are ADM mounts. The Trijicon and SWFA QD mounts are Bobro. SWFA had the Bobro extended mount for $209 the last time I checked.
