I bought a Mossberg 930 with a 18 in barrel and a 4+1 magazine tube. I would like to put a longer tube on it without being longer than the barrel. I was also thinking I would like a bracket to support the 2 tubes and possibly have a sling coupler. What are my best reliable choices? Any ideas?
Thanks

This interests me as well, I just bought a 590A1 18.5 and would like a flush tube extenstion.

Not sure if I need the +1 or +2 extension

Get a Nordic +2 extension and one if their mag clamps.

I would recommend Nordic as well, the price is worth it. I'm not sure if you can fit a +3 or not, but a +2 will certainly work as mentioned. You might get the +3 on there if you want it. It may stick out just slightly, but there's no harm in it aside from looks.

You can get the clamp as well if you want, but from my experience it's not necessary. I put a +4 extension on my Auto-5, where I cannot use a clamp due to recoiling barrel, and it took all of 10 minutes to install including the grinding I had to do (you won't) and has worked flawlessly since. Good product and well worth the extra money.

The Nordic extensions are vastly better than the Choate.

The Nordic ones come with the spring and instructions on trimming it to proper length. Not sure about the other manufacturers, but you should be able to ask them. If going with the Nordic option, be sure to buy the package/kit, not just the tube - that way you get the spring as well. Retail on the kits is around $75-80. Note also that if you want it quickly you might try ordering from Midway or another retailer. Nordic is a good company but they are swamped right now, took them a couple weeks to get it shipped to me.

It looks like Nordic it is.
