If this catches on...

...ammo prices will come down just like 300blk.

.... we’ll finally have a factory subsonic AR308 round (is there one already).

... suppressors for it will be more “normal” in that size.

Q seems to talk about this the most. Having more energy at normal hunting than a 308 while going subsonic from 12.5” barrel is interesting to many. I’ve not seen any benefit to a 308 SBR but this may be it.

That said, I’ll wait and see. And just like 300blk, it won’t be a range gun but serve a certain low-round count use.
