Many things to consider. Barrel wall thickness may require thin walled tubes. Briley does this work right. You will have several hundred dollars in this modification.I got a Baikal IZH-43 12ga I’d like to have barrels cut down to 19-20”, left barrel threaded for removable choke tubes, muzzles soldered/re-enforced, however that’s done, and new bead installed. Any Hoosier recommendations?
