That's great news, but not surprising, their CS is second to none, and has a well proven track record here!!!
The Williams WGRS sight that is standard on the BC, will mount in the two rear scope mount holes, as far as height, dunno, but you will probably want to loose the plastic front sight anyway and swap it for a Williams fiber optic sight, read the Peep and Fiber Optics sight thread in the FAQ and Help sticky for more info. :wink:
