re: Anyone own a Ruger American rifle?

Order this kit from Amazon:

Takes exactly 1/2 of the kit to fill the stock. I just removed the barrel/action, unscrewed the cheekpad and pulled out the pieces of styrofoam inside, and clamped the stock to a vertical surface. Mix A:B in equal parts and pour into the stock and let it setup for a day to cure. Feels like bathroom silicone caulking but no smell and it adds about a pound to the weight, seems to help with balance and recoil.

ETA: Order a spare magazine or two. Don't know if Ruger has improved them but the one that came with my rifle took a few range trips to work out and feed without hanging up the last round. The two I ordered extra functioned flawlessly.
