Since it seems impossible to find any weight kits for these stocks, I started making some for my rifles. I have a Centurion and a G2 and they fit great in both. I wanted to see if there was any interest out there to purchase these. They are made out of brass and the full kit (22 pieces) weighs 2lbs. I only used 10 pieces (.9lbs) in my Centurion and it worked great for the balance point I wanted to achieve. I have seen others silicone them in, but I used some All-Temp ultra thin tape to secure them in place and seems to work great. PM if interested. $80/(10 pieces) or $150/full set.
