Well I finally heard back from the gun shop where I had made an offer on a consignment Mod 12 and the offer was accepted. When the Gawd awful hunk of steal gets cut from the barl it will be a 22" vent rib. How bout the barls on these guns, are they able take screw in chokes ok? Also need to get a really fat bead for the front as my eyes are not as good as they used to be.
