If you're interested in alternatives to the Leupold 2-7 of similar size and quality; consider the Redfield Revolution 2-7, and the Weaver Classic 2-7. The Revolution series are made in Oregon by Leupold and carry the same lifetime warranty. A couple of our guns are wearing them now (one in 2-7, one in 3-9). I also like the Weaver 'Classic' line, and have had a couple of their fixed power scopes. These are made in Japan by Light Optic Works. Their variables seem of similar quality and clarity. Both the Redfields and Weavers are similar overall diameters to their Leupold counterparts, a little bit longer, and can be had for under $200. If you find them used, they are often much more reasonably priced than a similar used Leupold.
I generally use Leupold fixed power scopes on my rifles, though I have over the years tried others. The older, Colorado made Burris Mini/Compact/Short mag scopes in fixed powers probably had the slimmest ocular bells this side of a straight tube, and I do like them, but they tend to have restricted fields of view at any given range and power compared to others.
If you really want to see a scope that goes with your carbine like peanut butter goes with jelly, look for a used Leupold FXII 4X33. These are hands down my favorite hunting scopes; lightweight, compact, bright, clear, sharp, and super reliable.
