BudsGunShop.com - Threaded barrel?

I have not heard any news that they plan to. Though it just came out, so it might be some time before they discuss modifications or upgrades.

Ter, there is a high probability that Ruger will eventually add a threaded barrel. https://detroitammoco.com/product/new-subsonic-5-7x28mm/

Ter, I really doubt they will come out with one. Maybe down the road. No need for compensator with such a light recoiling round. And to use silencer on this supersonic round your still gonna have supersonic crack. I don't know of any sub sonic 57 ammo.
