Ruger SFAR 308

[ironman56]

I have I friend whose looking to get a AR308 ,he thinks my Areo 20in is a bit too heavy, so was asking about the Ruger, I was considering one myself before I built the Areo, but after reading about issues here decided against it, without reading the entire 700 + pages on the subject, my question is , is the ruger compatible with full size barrels , triggers and buttstocks ,as those are things that typically get changed to suit the owner, what say the Hide.

The barrel extension is proprietary.

Trigger and furniture are standard AR-15.

So barrel extension is proprietary, are there any quality aftermarket barrels available.?
