Lets the MPX and MCX share stocks because their stocks are all listed as being compatible on both MCX and MPX but actually aren't and it pissed me off.

Do be warned, the base MPX stock clips a little bit when applied to the MCX. The other MPX stocks also sit a little low on the MCX than they probably should, but they still look nice so eh. Not that big an issue.

Advanced Custom Weapons probably does this already, I dunno. At least, it should.
