Vortex Optics Viper Extended Cantilever AR Scope Mounts, 30mm CVP-30

Fits my scope like a glove.

The Vortex mount provides the flexibility to install your scope with the ideal eye relief. Height in my opinion is where it should be. Considering the cost of other mount sold, the Vortex mount is an excellent value with a lifetime warranty. If you don't want to break the bank, get a Vortex mount. You won't regret it.

When I got this mount I was immediately impressed with the overall build quality and the heavy (but not too heavy) weight. Don't get me wrong, this mount is pretty light and I don't consider it "heavy," but I mean that it didn't feel cheap. It was a good kind of heavy. One problem that I thought I had with the mount, was that the two ribs under the mount that are supposed to sit in the slot of the picatinny rail sections, didn't fit the full size of the gap like I thought they should. I gave Vortex a call and asked about the problem because the mount was sliding around when I had partially mounted it on my rail, and they said that the ribs actually are not supposed to sit flush inside the slots. Instead, the scope mount is supposed to sit forward against the rail and then tightened all the way. This seems a little bit odd to me, because if the scope were to suddenly get pressed backwards really fast from it falling or anything else, it might knock the mount backwards a little on the rail, and you wouldn't be able to notice. But I do trust the Vortex team, and if they say thats how it's supposed to be, then ok. I'll just have to secure it very tightly with some red lock tight to make sure it doesn't come loose at all.

This Vortex CVP-30 scope mount went right on my Diamondback DB10 (AR10 style) rifle with adequate clearance for a Vortex Diamonback 6-24x 50mm scope which has a 30mm tube. Perfect solution for adequate eye relief. This same scope / mount also fits on my Howa APC 1500 rifle in .308 caliber, again with adequate clearance. The mount included a little T15 Torx wrench for attachment to the scope. I used a screwdriver style torque driver to set the mounting screws to the recommended 15-18 in-lb torque. The two nuts which tighten the mount to the rifle picatinny rail are 1/2" hex nuts and the recommended torque is 25-35 in-lb. Again, I used a torque driver to set this in the middle of the range. The finish on the mount is excellent. I saw and felt no evidence of burrs or other defects on the rings. They went on the scope smoothly, and stayed in place after a few rounds. I checked the torque afterwards and ring screws were good... no apparent change. Good practice advises some blue loctite on the ring threads, and I'll probably end up putting some on. But my first impression of this mount and rig is excellent.

Have not put on AR yet! Waiting on scope to arrive. But overall seems like a well made mount.
