Anybody here have any experience with Night Forces's WedgePrism?
Thinking of getting one for my TRG 300 win mag.

I need to look that up. I'm not familiar with that "WedgePrism" What scope to they offer this in?

not a scope its a optic that is placed in front of the scope, increases MOA/MIL like a 20 MOA rail
allows for 50 MOA to 100 MOA increase. Its that or a American Rifle Company 40 MOA cantilever.

going to a 1x8" progressive twist barrel for 2000 yd.

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
