Redfield Palma & International Rear Sights

[Blackhawk]

I have several sets of older adjustable Redfield rifle rear sights, specifically the Redfield Palma, International, and Olympic models. I'd like to try these sights out by mounting to a rear rail on an AR, but have only found two rail adapters (Brownell's @ $80, and Accuracy Speaks @ POR). Does anyone know of other sources of a mount that would allow me to mount one of these Redfield rear sights on a rail (and not cost an arm and a leg just for experimenting)?

Thanks BKliebert, exactly what I was looking for. Don't know why I didn't check them (Champions Choice) already, as I've been buying from them since the late 80's.
