Mossberg 930 mag extension tube

[a1fabweld]

I just started my 10 day wait for my new Mossberg 930, which also happens to be my first shotgun. It has the 18.5" barrel & short mag tube. I would like to know if anyone has suggestions on the largest capacity mag extension tube I can install that won't extend past the end of the barrel. If possible could you list the manufacturer & part # as well? I searched briefly, but only came up with Choate's model. Thanks.

I have the Choate one as it was the only one I knew widely available. There are a few guys over on ARF that sold them in a limited run. Supposedly quality was high, but I had no personal experience.

I can tell you that mine works perfectly. I did trim their provided spring a bit though as it was WAY to long...

Mine is on a 930 with the breacher muzle device. The mag tube extends approx 1/2 inch past the barrel extension and is not overly noticeable. I have had zero issues with it.
