uber tactical turkey gun with M4 stock, fiber sights, spare shell holder and complete camo dip. the thing comes with a XXfull choke and even though it's amazing to have a 6 inch spread at 25 yards, I would like to try out trap shooting and am thinking about a full choke among other modifications

Otherwise, these folks might be better able to answer your other questions:
