If you're keeping it budget, that DNZ mount and a Nikon Buckmaster is a good combination. My personal feeling on the Vortex are that they're cheap scopes are a quality hit and miss. That's just my personal experience with those. I like the Vipers and have one that I really like. Anything from Burris is good to go. I like the Fullfields for a really tough scope. And '06 with a 2-7 or 3-9 Fullfield II would last you a lifetime.
