I was looking at getting a rifled choke tube for my MP-153 to give a bit more accuracy with slugs. When I go to pattern the gun, I'll grab a box or two to see how they do with the IC choke, but I was wanting to ask where a good place to get them is, and how well they work, vs smoothbore or rifled barrels(which isn't on the list, if I get a dedicated slug gun, I'll buy another shotgun).
