I am building a 6.5 prc for a lightweight backcountry pack gun and am debating between a Mesa Altitude stock or a XLR Element 3.0 Magnesium Chassis system in carbon. I am going to be hunting with a 7in suppressor so a folding stock of a chassis system would be nice. I have only hunted with stocks, and my concern is that the chassis system would be awkward to carry around with an over the should sling. I appreciate any feedback for the positives and negatives of each for a pack gun. TIA
