Sumtoy choke question

Just got a new Sumtoy choke in for shooting Federal Hvy 7s. Looking inside the choke I see grooves cut longway but also see rings cut around the inside of choke on the end that screws in. I'm sure they have a functional purpose.

Just curious if others have rings cut inside their choke tube.

Will it effect the wadding?

Wad strippers. They slow the wad down so that the shot is released.
