Kick's Chokes

I recently purchased a Kick's High Flyer choke. I'm a "Carlson's" man usually, but I got myself into a bind (need a certain choke and I'm in AR about to go smack some ducks) so I bought this one. I have a Browning A-5 Mag 12 Inv+ bbls, and when I screw the choke in it has a little bit of slop. When it is tightened down, it's good to go. Is this normal? I have Carlson's chokes for my 870 and INV bbls and there is no slop when installing them. Anyways, any advice, words of caution, experience, etc is greatly appreciated.
