Canted Scope Rail Question

Hello-

I've been thinking of buying my first rifle (coming from shooting handguns), so there are a number of things that I'm not familiar with. The rifle that I'm considering is advertised as having a scope rail with a 20 MOA elevation. The optic that I'm considering has 75 MOA of vertical adjustment.

Let's assume that the scope rail is flat instead and that the scope has a perfect zero at 100 yards, meaning that it is at 37.5 MOA of its total adjustment. With the 20 MOA scope base, does that mean that I have to adjust the scope down an additional 20 MOA, leaving me with only 17.5 MOA of remaining downward adjustment?

Thanks for any help.

Elevated scope rails are a pretty specialized thing. Unless you're shooting at very long ranges it's going to be more a a hassle than anything. BSW

Right, and that's why I was asking. It's not that I want an elevated rail, but it's all that the rifle comes with.

I'd probably accept the rifle with the elevated rail and see how it works out. You can always sell that rail and replace it with a straight one, right? It's not welded on or anything, right?

The product page states that it's attached with #8-40 screws, so yes, I assume that it could be removed.

Yes is the answer, unless you are shooting out to 500 or so yards.

At 100 and 200, if that rail was properly installed, you should have to LOWER the point of impact. And lower it a LOT. In fact, you may actually run out of adjustment before you are even on paper with it.

I had that happen at 250 yards with a 50 BMG I was sighting in for someone. That had like a $1,400 Leupold 6 x 24 I believe with illuminated mil-dot.
