Filling Void in Polymer Stock

I filled the butt stock of my Ruger Preditor rifle with a product called Smooth on Silicone mold making liquid rubber from Amazon. It cost around $26 for the 2.8 ounce two part mix. I put two 1/2" hot water pieces of pvc with tape on the end that went inside of the stock and lubricated them. once the material set I pulled the pvc pipe out of the material. I did this to create a couple of hollow tubes to act as dampeners. I used Rockcrete to fill the crossed sections in the forearm. I am very happy with the extra weight and the stiffening of the stock.

I've built a handful of Specialty Pistol stocks from cut down Choate Ultimate Varmint rifle stocks. My goal there is to stiffen and at the same time to add weight. I fill the larger areas with brass bar cut to fit the voids loosely and then fill around it with Devcon epoxy mixed with brass coated bb's. Becomes solid and adds the needed weight and will not break or move. it is permanent though.
