First, what caliber is it and what is the intended use? That should determine what kind/power scope to put on it. Is it a heavy barrel .223 or 22-250 that you intend to take for Prairie Dogs out at 500 -700 yards? If so you need up to a 20X or more and "good" glass, such as Leupold, Ziess, etc. If it's a standard barrel, and in .223 or similar and you plan for coyotes and other local varmints, probably a 4-12 power will suffice, and maybe you could get by with a little less quality in the glass. If it's a larger caliber to use for deer sized game you won't be taking more than a 200 yd. shot so you can get by with a 3-9. If it's a heavy caliber like a .416 Rigby, to be used on dangerous game, you probably only want a 2X or 3X scope, but the highest grade rugged glass you can buy. My theory is to match the glass to the purpose, but always buy quality. Also, don't skimp on the mounts, get a full bridge mount, and heavy double screw rings. Cost a little more, but the first time you drop it on a hunt you will be glad you did.

I concur with these statements. We need to know the chamber of that new 700 and just what you plan on doing with it in the future. You do get what you pay for in optics, 98 % of the time. Do not buy cheap to put on a new 700 Remington. I have about 15-18 Leopold's that I have accumulated in the past 45 years of all ages and size. All have preformed without any problems, but the Two Ziess scopes I hunt big game with are a noticeable superiority at dusk and dark that their equivalent new scopes in Léopold. Check weight for your purchase if you have any plans to carry your rifle in the field.
