    I don't know if there is one specific to the MVP but I would thing any 5.56 chamber guage would work (I'm drawing a blank as to if that is the correct term or not). Check Brownells. I'm pretty sure they would have what you are looking for.

    Low tech, but a Hornady OAL guage will get you in the neighborhood.
