Perazzi adjustable rib MX10 barrel. Came off a European gun and even though it was an MX10 this rib is closer to an RS than a standard MX10. Serial #88641 but gun was pristine. This also has the adjustable tabs that do NOT require the tool to adjust the rib, you can do it by hand Specs: 18.4 bore 11x11 rib fixed choke .030 bottom and .040 top Barrel weighs 1.552KG Barrel is in excellent condition $4495
What is the barrel length,thank you. OH one more question. You say .030 and .040 constriction bottom and top so this would be .694 and .684 , seems pretty tight .
this is a 29.5 inch barrel my choke constrictions are accurate. Yes tight barrel, my guess a bunker or live bird barrel
