I'm looking for a sniper scope for my Ar15 that will be shooting .223 rounds. I'm wanting this to shoot out as far as possible with a 20 inch heavy barrel. I have two uppers, 1 in 7 twist and 1 in 9 twist. I'm wanting a dedicated scope built for the .223/5.56 rounds. I have heard there is one built strictly for the Ar15 platform and comes with a program for your computer that gives you estimates on your reloads and factory ammo. Anyone heard of such an animal?
Nikon makes the p-223 & m-223 series which are good. I have a fixed 6X power from primary arms that is made for the .223. I really like it.

Any BDC type reticle will work for your AR, just depends on what you want to really do with it. The factory tests with the dots elevations will differentiate with your own barrel. So what you will have to do is go to a gun range and sight in your rifle with each dot on the reticle to know excactly what yardage they will be zeroed at. And test, test, test.
