So I had nothing better to do and checked out the scopes they had.
For an AR (depending on what use you come back with), choosing only from the Bass Pro Shops website, this one is my personal choice...
Burris Fullfield II 3-9x40 with Ballistic Plex reticle (38-802-678-00)
This is one that I have used even though I wasn't stuck with choosing from one place. The glass is very clear and bright, and the ballistic plex reticle works well on an AR. I will be putting one on my AR10 soon.
Besides that one, I also would trust these:
Leupold Rifleman 2-7x33
Bushnell Elite 1.5-4.5x32
Nikon Buckmaster 3-9x40
I know I said I like lower powered optics, but there wasn't much of that to choose from. Now I know this is breaking the rules on ARFCOM, but if your rifle is JUST FOR PLINKING and shooting for fun at the range, you might be interested in one of the Bushnell red dot sights. I've done a lot of research on the Bushnell with the 4 interchangeable reticles (red only, NOT red and green) for a Beretta Storm I had, and the reviews I read were positive. Again, depends on your use.
I have never seen anyone have much luck using a scope on a bolt-gun and an AR because the rings are SO different. I'd suggest purchasing a separate scope with that extra $250 you mentioned.
