anyone seen the "paradox" choke? supposed to be rifled for slugs.... was listed in the factory paperwork that came with gun. all my gun had was a thread protector ring on it when new, never had a choke tube.
dont know if it helps, but ive fired standard remington "slugger" slugs out of my s12 with no choke on it and all were within 8-10 inch @100 yds....no choke just smoothbore.
