First attempt was to fill the bottome metal and mag slot with Bondo type stuff. I noticed that it cracked in a couple of places after curing. (I was warned of that) After about 25 shots there is a crack all the way around adn the finish is chipped all the way around but the finish is no biggie. I figure a few more shots and it will fall out. The whole idea was to stiffen the stock. Any advice other than a new/different ADL stock. I have way too much work into this one already and really like the way it shaped up and feels to give up now.
