thanks for the compliment, it's a now discontinued wood stock from Rock River Arms.
you're very welcome for the info, be sure to post scores
I never have shot with the Airforce to I can't really vouch for how or possibly why they are different. I guess Marines M9 qualifications are close enough that they can take a Navy Qualification and submit the score card to their command where they don't have access to a range with Marines qualification course. soon after I qualified on active duty a friend in my work center wanted to go and I went with him for moral support as he failed his qualification in boot camp and was nervous around guns. when he was shooting there were 2 uniformed marines in his group so I'm guessing that their qualifications are similar enough to substitute one for the other...
