RE: new rifle needs new scope
CTY - There is nothing wrong with either the NIkon or the Burris. I have Leupolds VX-II, Nikon Prostaff, and Burris Fullfield II scopes. I like them all. They all have good optics. I actually have 3 of the Burris Fullfield II scopes with the BDC reticle. And you will find that if you choose this one, the BDC works just as described for your .270 (which is also and excellent cartridge). You will not be sorry with that combination of scope and rifle/chambering.
As for a Realtree finish, that's totally up to you. I personally like a scope with a matte finish.
