We will be out of stock of R-10 Lower Receivers for the time being. We are converting the raw material of both our receivers from extrusions to forgings.  This change in raw material forming requires finding a new supplier and a design change. Our current best estimate for availability is fall of 2025. Check back here for updates or sign up to our Newsletter to be notified when exactly lower receivers and rifles will become available again. It will be worth the wait!
