I ordered and received the Witness Pro. Although EAA said it's a Stock II upper, it's actually a Stock I upper. Cone barrel with polygonal rifling, full-length guide rod, Stock I sight. Build quality is excellent. The internal trigger parts are covered in a slick polycoat that is not very slick.
The trigger isn't bad, but it isn't good either. Gonna require some work. So I've disassembled all the lower parts to polish them and to put in some lighter springs: TRS, sear, hammer, and trigger plunger. I'll give a range report this weekend.
the shiny on the rails is from me doing some initial lapping of the slide/frame fit with Flitz.
