my dad has a 20 ga remington 1100 3" mag semi auto, with a polychoke he will sell...
long story short, lent it to a buddy, who got snow in the barrel, who then shot it, ruined the last inch of the barrel, so it was cut off and a polychoke was installed many years ago...
gun has sat in the cabinet ever since except for a few times my mom wanted to trap shoot... which doesnt happen any more.. lol
anyways, its sitting there, he MIGHT have another barrel 2 3/4" for it... not sure, but if you are interested (i know its a remington and you dont like them) ill get him to give me a asking price...
(remington is all i shoot.. i feel they are top notch, personally)
