Works great for the Ruger SFAR

Was having pretty jarring recoil in my Ruger SFAR (308) and got this stock for it. The recoil impulse went from a sharp impact + big push, to just a big push, making it much more comfortable to shoot. Stock works just as advertised, very satisfied.

I have not used it yet, but it feels like it is going take my AR over the top. As with all my previous purchases from FAB DEFENSE, they are all well-made, extremely durable, fit like a glove, and engineered to work the way YOU want them to. I like all of my purchases, but I really LOVE the rubberized textured products !!!
