I recently purchased a Nuprol Hun case for my competition Benchrest Air Rifle. Finding that I couldn't close the case effectively with the supplied foam a fellow shooter recommended Shadowfoam to me. I made the purchase of the Black and Green, to match my rifle, and then spent several days nervously trying to get the courage to cut it, afraid of making a very expensive mistake... My fears were unfounded, once I started the process was very simple and fantastically neat. I am extremely impressed with both the ease of making the cut outs and the finish. Now my case shuts with ease with everything secure, and also looks amazing. I can't recommend Shadow Foam enough.. 5* for both product and service. Thank you.
