Barrels are hard to find but there is an alternative.

Here is a conversation I had with Colonial Arms about making a "long choke tube" that could be soldered in and the barrel refinished. Sort of a mono blocking at 23"! It's cheap enough and but even a good refinish job might be visible in the right light.

Im looking for a custom tube for a 20 gauge that
would be your regular .675 x 44 tube but would be
extended 3" with no ports and choked skeet. Outside
diameter would be .715 .

Would this be doable and what would the cost be.

Thanks

Good Morning!
I believe we can handle this for you; however, it would have to wait
until
we ran 20TSPT1 again. The cost should still run in the neighborhood of
$45.50. Thank you and have a great day!
