I attempted to bed the L bracket on a centerfeed blind mag stock. The bedding was so thin in that area, the majority of it chipped out when I was cleaning the area. The ramps on both sides of the bracket are intact. I tried filling the mag well with foam, and used play doh for filling in the gaps I didn't want filled. The play doh failed, bedding was oozing into places I didn't want it to be. I was moving very quickly to pull the action away and fix the mess. Lesson learned, don't use play doh over foam. Use modeling clay or something more substantial. I probably won't use play doh in the future for any parts of the action or stock.
