That last post is a bit confusing. The Nightforce Wedge Prism is an optic that is installed in front of a scope to shift the image for long range shooting. It comes in 50MOA or 100MOA shift. The ARC 40MOA is not a cantilever, it's a canted rail. I am not familiar with ARC, but their website shows rails in 20MOA, 30MOA and 45MOA.
Ill take that as a No experience with the Prism
Wasn't talking about ARC rails --- was referring to the M-Brace. Looks like a cantilever in their pictures. The two rings are connected to the mounting base, like a Sphur or Warne, and have inclination built into the unit. 20Moa, 30 moa, up to 60 moa
