I just bought the same one, says "first anniversary edition" down the side. I was surprised it was only out for a year... I thought this was a bit older.
I'll be bringing it to the range for the first time this weekend.
Any issues with the rear sight not adjusting for elevation? That surprised me a bit. I'm wondering if I'll want to get a replacement for that, or just put a red dot scope on top. (What is a good mount that converts the top to picatinny?)
This should help with your rear sight and scope mount questions...
(I have an ATI mount and Sightmark red dot on mine)
