I've been very interested in the SFAR also and waiting to see some reviews. Please let us know what you figure out. Sounds like Ruger has at least been good to deal with?
Ruger’s Customer Service has always been excellent.
I’ve also been interested in the SFAR .308.
Another member here gave a review of the 16” version. His accuracy seemed much better with Factory Ammo, IIRC.
I’ll have to go back and look it up now.
