Anyone have the new Nightforce Beast?

Thanks Drifter once again.

When scoping an AR-15, pay close attention to the two things: scope height and eye relief. For height, the centerline of the scope needs to be ~1.5" above the rail. Eye relief seems simple enough, but you want the mount to be in contact with only the upper receiver (and not the handguard). The AR-specific cantilever-style mounts from LaRue, ADM, Bobro, etc are designed to address both aspects (height and eye relief), and many models have a quick-detach feature that return-to-zero amazingly well when removed and replaced.

The rings that come with a Nightforce scope are too low for the AR-15 without some type of riser. Nightforce offers an AR-type cantilever mount, though I don't think they have a QD feature (which may or may not be desirable for you).

Great info on the mount Drifter. Haven't read those measurements (1.5" to Center above rail correct?) and I like the quick disconnects to put the scope away when it goes into the safe. Scopes cluncking together in the gun safe when other uppers are being used isn't desired.

...1.5" to Center above rail correct?...

Yes, + or - 0.1" for most people.

Not sure if the chart on this link stays updated, but it serves as a good general guideline regarding AR mounts:
