Blackhawk stock and Burris fast fire

[wbralo]

I have a blackhawk spec op gen 2 on my 870 and was was thinking about adding a Burris ff2 or ff3 to the set up. Is any one using the blackhawk stocks with the burris optics? Also what would you suggest on the mounting of the Burris and would you go with the FFII or FFIII?

I had a bsquare mount and trueglo red dot but it sits up way to high. I could not rest my cheek on the stock and really didn't like the set up.

Thanks for your help
