Thanks for the input. I figured it out and it was definitely operator error. Everything is rock solid now.

I just attempted to install a Briley 8 round extension tube on my SBEII and all went well except.... The tune does not full lock fore-end stock on the gun. I have an eighth inch or less of movement with stock. Disappointed to say the least. I am not sure if I did something wrong, but everything is locked down tight except the stock. Anyone have this issue? Any solutions? Thnx
