I own a Ruger 7mm that was customized by the same individual who builds the USMC M40 sniper rifles. The barrel has been floated, the stock has been glass bedded and the trigger lightened for a smooth and easy pull.
I've put about 60-80 rounds through it. It looks great and has only minor flaws on the outside of the barrel and stock from moving and regular use.
Everything is clean, functions perfectly, and this rifle shoots fantastic.
