I bought an older 500AT that had a 28" barrel. Made a "riot gun" out of it, cutting it down to 18". Had a non-ribbed barrel. Gun was ratty so I sold it. My dot was 10 when that pic was taken giving me her "mean" look. I let her hip fire it once and she almost dropped it! She initially wanted to put it up against her shoulder until I talked her out of it!
The 2 barrels are a "before and after" of a NEF single-shot 12ga (I had 2 of the same exact gun). I use a (perfectly square) horizontal bandsaw and deburr tool and wheel, then some cold blue. Note I remounted the sight. I keep new Mossy beads in stock (with drill and tap) because they are a smaller tap size and could always be enlarged, if necessary. I have some 90^ blocks I use to assure the sight is perfectly upright. I've done a dozen or so barrels and they all came out similar to the NEF (OEM-ish)...
