Have been using the Ruger GSR for some time now, like it enough to now own three. Took one to Gunsite for the class, learned a whole lot. Have had very successful hunting with them as well. I prefer the Alpha magazines, and use Leupold 1.5-5 VXR IER optics.
The rifles have proven to be very durable, accurate, and reliable. For use on the ranch, rough service getting in and out of jeeps, and occasionally in horse scabbards and wet weather, they have excelled.
Yes, they cost more than some others, but to my experience you have to spend some money to get something that will last.
