Re: Need Advice on a Build
The 20 MOA rail will get you to 1000 yards and beyond. The 40 MOA rail is for getting everything out of your rifle that it is capable of. I have a Savage 300 wm with a 20 moa rail and I am over 1000 yards. The Nightforce has a lot of internal adjustment so it will get you out there. I am not sure what rings will be needed with the 56mm objective; you may have to go with high rings to make that work, but I am not sure. Calling Nightforce may help with that.
