I posted this on AR-10 but this is probably a better place for it.

Went to a trade show today and had a chance to look at the new Redfield scopes. They seem to be very nicely made, and the optics are excellent. A perfectly clear field right to the very edge. Retail should be around $200 and they have the Leupold lifetime guarantee. This is really nice glass at a very affordable price. If your looking to scope an ar at a reasonable price this is a good choice.
