Agreed, but everybody already makes bull barrel stocks for a 10/22. It just seems crazy to come out with a new barrel that doesn't work with all the existing stocks out there.If there's interest, there will be aftermarket stocks, just like with every other new product.
Maybe Ruger did it on purpose though. If they come out with a line of different stocks for this barrel right when the barrel is released, they'll be the only game in town until the aftermarket guys can design and start producing something.
