F/S K80 30" sporting barrel with Briley sub gauge tubes cased

I have a 30" K80 12 gauge sporting barrel with Briley sub gauge tubes and 4 chokes per gauge. Sub gauge chokes are 2 skeet,1 Imp skeet and 1 light skeet per gauge. 12 Ga. has 5 chokes 0,0,1,1,2. Wrenches and knock out tools included. All in a Krieghoff branded Americase. Case has slot for complete gun and 2 barrels as well as the sub gauge tubes. the 30" 12 gauge barrel is very nice except a couple small dings on side of rib. Only seen from side. Pics show the dings. 4500.00 shipped UPS insured.

 

What do the skeet tubes weigh? Which rib is on the Krieghoff barrel?

 

One 20 Ga. tube weighs just over 6 ounces with a skeet choke installed.

 

O.K. so with 2 tubes, weight would be 12-14oz, same as ultralites. Looked at the barrel pics again and it appears the rib is a 12x12. Is that correct?

 

12-8 is rib taper
