Frog,
I would love to have a 18-20" with the vent rib and screw in chokes . I am stuck on the rib so I can mount slug sights with no major mods to the gun . Does the factory make such an animal ? I know that part of the fun with these is being able to make what you want . I would give up the ideal length to have something i could screw on sights for deer , tight choke for gobblers , or improved for in your face bunnies or doves .
