Thank you! I used epoxy putty for the palm swell portion, and filled in with fiberglass hair bondo for everything else. It did help with the flex actually, It probably has something to do with such a large amount of bondo and epoxy on that area now. I really like it, and I can say from experience that it has just as comfortable grip now as you would find on any replacement tactical precision style stock. It shoots like a whole new gun.
