I just looked at my BC to check the staking that was done by the people at Rock River. To me, it looks like they half assed it. All they did was put a slight nick in the key, there was absolutely no metal hanging over the screws to keep them from coming loose. I have never staked a key before, but I don't know anyone to do it for me. I pretty much know how it is done and have an idea of how it should look if done properly. I have fired about 400 rounds though the gun, so I was wondering would it be best to check the screws with a hex key before staking. Also, could someone please let me know what would be the best tool to use and give me a few instructions on how to secure the carrier before I get started.
