Not a shotgun expert, but I have a Mossberg 9200A1 Jungle Gun that I cherish for some reason. Bought it new and got the Choate folding stock and an extra barrel on closeout for $50.

Now, I'm thinking cutting the spare barrel down to 12" and putting the folding stock on it would make a cool fun gun.

Obviously, cutting it like that would get rid of any choke it had (IC?), so is getting the barrel, which is pretty heavy, threaded for chokes a good idea?

From what I gather, Rem-chokes are pretty standard, so who can  cut and thread the barrel for chokes?

And don't say any competent local gunsmith, because I haven't found one of those yet, lol.

If you are a competent local gunsmith in the N metro ATL area, feel free to reach out.

Rose Action Sports.

They can do it all

Third vote for Steve @ Rose Action Sports, Don't bother sending it anywhere else.

Fourth for Rose Action Sports. He did my shockwave barrel up for chokes and it's been great!

Looks like it. Can they do engraving?

You’ll have to ask but I don’t think so.

Paging @GunCat

I get my engraving done at Tar Heel State Firearms.

I had him thread an old cut down mossberg 500 barrel for me with a mossberg style threading. So don’t just assume you will have to go to a fifteenth make unless you want to.

He can’t/won’t do Benelli Crio threading because apparently the taps are unobtanium.

He did my M2 with TruChoke threading, which is apparently the same as Remington.
