I have a sub gauge carrier barrel for a DT11 for sale. Barrel is 32"s with Briley ultra lite sub gauge tubes. It is a carrier barrel only. Will NOT fire 12 gauge ammo. It is matched weight to weigh same as a 32" choke tubed barrel with 2 extended chokes installed. Both the 28 and 410 tubes come with 4 chokes each. The 20 gauge only has 2 chokes. The Negrini fitted case has 33 1/4" barrel slots. Comes with hammer and knock out tool. If anyone wonders it was just under 8000.00 to pull the project off. Just don't shoot sub gauge at all. May have 500 shells thru tubes and mostly the 28 gauge. I will take 5000.00 for it plus actual UPS insured shipping to your address. Not interested in offers. I will keep it before losing more.
