No choke restriction, you can fire slugs or less-lethal ammo through it also. It tightens patterns about as much as a modified choke on most shotguns though. I use a 20" shotgun with a KA-1212 for dove hunting and run neck-and-neck with the 28" choked guns no problem. They weren't designed for hunting 4-legged critters or birds, but a lot of people use them for that as well.
Not Choke "restriction" Choke "constriction" as I said. What does it mic out at?
