I want to get your suggestion for a good cantilever 30mm scope mount. The scope is a Vortex PST gen2 5x25x50. This is going on an AR10.

I have the Burris QD p.r.p.r QD mount already on an AR15 and was thinking of another Burris prpr mount but non QD.

I like how the Burris uses 12 screws instead of 8, but I'd prefer a U.S made mount. The scope is about $1000 so I was thinking of spending more on the mount.

Any suggestions for a Cantilever 30mm mount?
