I was doing the other post from memory. The guy I got it from said it was IM Mod but I have not measured the chokes. I don't know if anything was done to it. Will have to have my smith measure it. I don't like opening up the guns that I own because we have such a variety of birds that we hunt here in the midwest US. I have had very good success using the polywad disc that you put on top of the shot column. I roll crimp it so that it becomes the overshot shot card for my application. You always know you are shooting a spreader that way when you are loading your shotgun. This gun worked very well on the quail that I shot recently.
