Yes, I own a BR model in 12x42/56mm with an NP1-RR reticle. I used it last season in conventional LR highpower with good success out to 1,000. As with all Nighforce scopes I've seen it's clear, sharp, & tough.
The ranging reticle seems very user friendly to me, much more so than mildots which are a perishable skill unless practiced with regularity - which I don't anymore. It's fast & easy to use with the holdover marks: instead of counting inches & MOA, take the range, calculate the MOA over, hold on the correct MOA mark & shoot! I'm hoping to really wring it out in the next few months, but it works especially well at mid-ranges.
