I own one and I love it. It is quite light and handy to pack around the woods and was a joy to maneuver in and out of tree stands. As far as it not being suitable for hunting, I have some deer in the freezer that would disagree with that assessment.
There is a lot of hand wringing about loss of velocity and "losing the long range ability of the .308". This is not a 1000 yard rifle, doesn't claim to be, but it is more than capable at typical hunting ranges. Long range rifles are specialized tools, the GSR is more of a utility rifle and can fill a lot of roles.
When it first came out, the mag choices were limited and expensive. Now Ruger makes polymer 3, 5 and 10 round mags that are much more reasonably priced. For those who don't like the look of the mag extending out of the rifle, or like to carry the rifle at the balance point, the 3 round mag is flush fit.
The laminated stock is very nice and comes with 3 different pads to adjust for pull length. The trigger is great, breaks very cleanly. The forward rail allows for a variety of optics and both eyes open shooting, or you can mount a traditional scope. A lot of people mount the IER scopes on the rail, I think I am going to mount a Lucid Red Dot with 2x magnifier and see how that works.
The flash hider bothers some people for some reason. It is threaded, take it off and put a nut on there to protect the threads. Problem solved. I plan on taking it off and threading a suppressor on there myself, but until then I have no problem with it as is.
If it is not your cup of tea, fine, but seriously, so much angst over this rifle, I don't get it. There are a lot of guns that I don't like or don't feel the need to own, but if someone else does, great.
As far as the kick, I did not notice anything different from my other .308's, the recoil pad is thick and really soaks up the recoil. This gun is a bit louder, as you might imagine, but my buddies in hunting camp expected it to be much louder than it was, so it couldn't have been that bad.
