I have the Mil-dot on the .338 Lapua and my 700 in .308. I just put an 8-32x56 NXS with zero-stop on my AR-10T and that has the NPR-1 reticle. I like the Mil-dot better, but all Sniperco had in stock was the NPR-1.
All I have is a thing that replaces the front sling mount and allows the bi pod to attach to it. Sorry for lack of technical terms. My dad bought the part at pop guns and they even installed it for us, that was... 5 or so years ago and I don't remember what it's called.
