Just got one finally with the rangefinding NP-R2 reticle. I mounted it on my Rem700 ADL 300WM for now. It's on a two piece Leopold base with Leopold QR rings. The MK4 rings were 168.00!! I'll wait and see. The scope zeroed bore sighting it at 46moa up and 2moa left. I need a tapored base now for sure. The scope only had about 91 moa total elevation not 100 as advertised, and windage was a little short too. All said, I'm very happy so far! I'll be doing some serious testing of the ranging capabilities with this reticle in the near future and will post more results.
