How much do you want to spend?

I used to have a couple of 222s, a Remington 660 with a Weaver K6 and a Remington 700V with a Weaver K10. My most frequently used 223s have 4-12x40s and 4-16x42AOs on them. If you don't need turrets, I think that the Sightron S1 4-12x40AO is a nice scope for under $200.
