thank you for your responces. there are a couple of things though, they seem to only be avalible in the syntetic stock version, and the 20ga isnt threaded for screw in chokes. doesnt seem to be much of a weight difference between the 20 and the 12 though. beeing around 8lbs do you guys use bipods or freehand ? the screw in chokes will be my deciding factor ( more versital, cabelas new book has a screw in poly choke cyl-ext full at a twist )
