I want to replace the extension tube that came with my 930spx with a Nordic tube. When I go to Nordic's site it was unclear which size best matches the +7 choate tube that came with my SPX. Anyone have one or a clue what I should choose from Nordic ?.
Plenty of folks run em past the barrel, but dont know about anyone here. I have seen the Nordic extensions on plenty of Benellis that run longer and I'm pretty sure on a few 930's too.
