Autoloaders are all drilled about right there. Might be a candidate for welding.


That's what I was thinking as well, though I'm certainly not an expert. The barrels may be salvageable and usable in 12 ga. Of course, if you get the 20 ga tubes, you could still use them, whether the 12 ga barrels can be fired in or not.

Like the 28 Ga? Check it out:
