I just ordered at set from eBay for $18.95 shipped. Will post results once I've tried them.
My intent for the sights is purely for looks, as they'll be stuck beneath a PA 1x4 scope. But I plan to try sighting them just to see what the difference may be? My guess is there won't be much if any. I'm betting they're the exact same thing as the MOE, just made in China.
