29.5” type 4 over under barrels from an MT6 18.4 bore with factory choke tubes #4 and #6 included Stamped 1.49 kg and weigh 1.507 on my scale. Rib is parallel and 11mm barrels have blue wear around the chamber area, looks like cold blue was used on the area at some point. there is pitting along the side of the rib at the chamber end (pictured) bores are in good shape and the barrel is mechanically sound. $1650 shipped. Can deliver to the grand or cardinal center if desired.
To clarify these are type 4 barrels which will fit any current generation type 4 square block receiver/iron (with proper fitting) these are not for the older striped receiver MT6 here’s a pic of them on an MX10
