16 Gauge A5 Choke Replacement: Finding the Right Fit

Question
I have a 16 gauge A5 with a cutts compensator and what looks like a screw-in choke.  Where can I find someplace that would have replacement chokes?  Full choke is nice if you are really trying to reach out, but I'm using it exclusively for sporting clays and would much rather have a modified cylinder or improved cylinder.

Answer
Nick,

I am at a loss trying to recommend a source. I would suggest looking at GunDigest Magazine. Often times you will find numerous parts dealers in various ads. If you are anywhere near the Tulsa Arms show this weekend the chokes you need will be there.
