What's you're intention for the gun? Will you need high magnification? Large objective? Decide on the needs and you'll weed out a lot of options. For an all around plinker, I'd go with a standard 3-9x40 or perhaps a 2-7x32. Mate the level of the scope to that of the rest of the gun. In other words, don't skimp and go with a $25 no-name but going with a Zeiss would be quite overkill. I'd start at a Mueller as a minimum. Very nice optics for the price. From there, Weaver or Nikon even a Burris (my preferred option)
Something to consider...poor optics are only magnified with increased power.
