This is a 32" 12 gauge barrel with tapered, Tramline rib. It was overbored by Briley & fitted with small gauge tubes in 20, 28, & .410. The tubes are their Ultimate Ultralight that sell for $1750. It was altered so that it will not accept 12 gauge shells.
This setup weighs the same as my normal 32" barrel which is 1.580 KG. This is the ideal package for shooting small gauge Sporting Clays events. An extruded aluminum case for the tubes is included. It was made by AmeriCase. Chokes are also included as are the tools for installation & removal.
This barrel & tubes has only been used twice. There have been approx. 400 shells fired through it.
