I am putting a US Optics B-25 on an AR10, it has full length pic rail. I want the scope system to be good to at least 1000yds[ preferable 1500yds if optics won't get too weird at 100yds, ] The turret area of the scope looks long.
 
For my purpose it was because I have a 13.5" length of pull and the scope has about 3.5" of eye relief. I originally contacted Spuhr and started with a 4603B mount, which is not a cantilever, but the scope was further back then I wanted. Here is my original post with the 4603B non-cantilever mount if it helps, you may have already seen it.

Just so you know, Spuhr makes the 4616 with quick disconnects and they may have the 4603B with QD's? Also note that the mounts I am using have a 20.6 MOA/6 mil mount for the +1,000 yrd. They may have other models if you don't want the rise in the mount. Spuhr is great to work with. I would send an email and have a response the next day because of the time difference.

Also wanted to share that for me, the anti-cant level in the mount isn't easy to see with the big eyepiece on the US Optics scope so I added the Knights anti-cant level. Much better.
