Tubesets for 12Ga. Guns (Includes 20ga., 28ga ) Briley Ultralite

Briley sub gauge tube set , like new with chokes  - 20 ga. and 28 ga.  came off of a Perazzi  MX3 with 29.5 inch barrells -  The diameter of the front of the tube is .623 .   Have your gunsmith fit a set of chokes in your gun to .623 and you now have 3 gauges with little weight difference.  I believe they can be installed on a 30 inch barrell also.
