I just picked up a M590a1 last week that had been threaded for Remington chokes from the last owner. Haven't used it yet though.
No problem with the chokes I bought. Can get them in and out easily.
Didn't mean to make two post, but here are a couple pictures of the work Tac Ord did on my 590 mariner. Neat job and fast turn around. I've not shot it yet but certainly look forward to it. Casey was great to deal with and I would not hesitate to send him something else to work on.
Measure the outside diameter of the barrel. If it's greater that .845 you can get it threaded for RemChokes. If less than .845, but greater that .825 then you can get TruChokes installed.
I currently ream and thread for Rem, but I have Just ordered the reamer and tap for TruChoke because there are so many older guns out there with thinner barrels.
The above are minimum OD specifications but there is another thing you have to consider and that is the screw in bead. If you ream and make the wall too thin then the front sight will fall out. On this job that was a major consideration.

Very true. With barrels that have been too thin to bead, I will often solder on a raised sight.
In one circumstance, the owner just wanted the gun with a full choke, and didn't need the option to change chokes...so i installed the bead directly through the barrel and choke.
