Pattern Master Choke tube! !

VERY, very good for large shot.

I think both those sights would work well, use which ever you like best.

If you reload I'd suggest buying some BBB or T shot from Ballistic Products.....copper or nickel plated preferred. T shot gives denser patterns than 4 buck & at any range you don't have enough penetration, you don't have enough pattern density from 4 buck.
