Hell NO, no tube sets.
Go to any sporting clays event and try to shoot your 410 or 28 SxS against the guy with the 11 pound target gun with a set of full length tubes and see who wins that one. I think it should be about the gun, not the score that you can achieve with your best 12 gauge gun. Although I do understand it could be an affordability issue for some and an inconvenience for others, like myself, to ship several guns across the country to compete in an event, but my god can't we be true to something in the country.
