Syren elos extendable choke tubes

[Tradchef]

My late father’s wife just picked up a Syren Elos D2 Field in 20 gauge. I know she is wanting to get extendable choke tubes for it. Aside from the ones I see on the website is there any aftermarket tubes that would fit or that any of you suggest?

That is a huge can of worms talking choke tubes. Thing with chokes is every gun likes something a little different. I would assume most major choke brands have tubes that would fit. Just need to confirm the threads that gun uses, several different thread patterns amongst brands.

What is the intended use?
