I just picked up a 12ga Stoeger single shot with interchangeable chokes. It came with a modified choke in it but no other chokes & no wrench. I tried my Mossberg choke wrench, but it didn't fit & I couldn't find anything listed on the Stoger website so I'm wondering what else might work. I did read that Mossberg & Winchester chokes fit the Stoeger BD's & O/U's, but nothing in respect to the single shot, are they the same? Any help is greatly appreciated. Thanks, Brett
