Anyone know why the New Jersey compliant M&P 15 II ships with an aluminum mag rather than a 10 round Pmag. Looks like the standard rifle comes with a 30 round Pmag. Just curious.
Most likely, it's a matter of cost. And are you sure it's a aluminum mag? When I bought my Sport II back in '16, it came with a Stainless Steel ASC 10rndr.
