I'm not a big fan of Swift scopes. I consider them to be a bit better than Simmons, but that doesn't say much. The reason I say this is because I have some experience with them. Specifically, the tracking was not very good, and that was on a relatively light kicking rifle - a .270 Winchester. Granted, your .223 is a lighter recoiling rifle, but still - if you can spend a little bit more, you can get a better scope.
