Is there a favorite out there? My often neglected tac shotgun needs a little love and for sure this is the first step needed.
I have used both of the following on my Mossberg 590 and 930:

I also like the nordic barrel clamp with picatinny rail for weapon mounted lights.

Thank you, any preference between the two?
I have the S&J on the 590 (fixed +2 extension), and the Nordic on the 930 (also fixed +2 extension, I don't currently see on Nordic's website), they both do what they are supposed to and quality is, in my opinion excellent on both. If you just want the +2 mag tube, I would probably recommend the S&J because it is a complete kit (Extension Tube, Spring and Follower) according to their website.
I think the Nordic MXT gives more "customization" in regards to mag length vs your specific barrel length. In other words, you can decide whether you want the mag length shorter than, equal to or longer than the barrel. But, you need to buy separate components to complete the install (Tube and Nut)
I highly recommend the barrel clamp with or without rail for the added support to the extended mag tube.
Magpul also has a barrel clamp/sling mount (depending on what type of sling attachment you want/need) but it does not have pic rail.

Hope this helps and good luck.
