RE: adjustable choke tube ?
I have a friend that has one that is made into his barrel(I think a Winchester).It comes in handy if you are hunting squirrels,quail,pheasants,rabbits,or especially dove,you may like it.Since depending on how high birds are flying or terrain like tightening the choke to shoot squirrels out of the tops of trees,and then stalking back through the thicker trees you can open it back up.Tru glo says theirs takes hevi-shot too,so it may be worth a try to see how it would do for turkeys.
