Hello, I'm using your question because it has the mag tube related to my question(hope you don't mind). I have a 1972 model Mossberg New Haven 600A that has the 5 shell mag tube that has the ring stop and spring for the action tube on it. I am looking to upgrade it to the 20" barrel so I can use the 7 shot mag tube (not count chambered shell) that comes as a set from Brownells. (question) is there any reason the action tube(7 3/4") that I have would not work on the newer mag tubes that no longer use action stop rings? For anyone not aware of the Mossberg New Havens its the 500 built for Montgomery Ward Dept. store, and if it fits the 500A it fits the 600A. All my internal receiver parts I upgraded to the newer 500A model parts. I could resale my 18 1/2" barrel where I live in Ga. easily for $70 or more and end up with only $30+shipping in the 20" barrel mag set. thank you for anyone's help with this.Re: What magazine extension tube to get for Mossberg 500?

Midway USA has the 8 shot extension tube but I am not sure that is long enough to accommodate the CDM gear mount.
