Assuming the RRA has been set up for reliability (i.e., you had someone stake the gas key and castle nut, since RRA doesn't often do that right from the factory, and you paid the extra $40 for a chrome-lined 5.56x45mm barrel), I'd take the RRA.
With a loaded 30-round magazine inserted, the AK will weigh nine or ten pounds in that configuration, plus 300 rounds of 7.62x39mm in an ammo can (almost twice as heavy as 300 rounds of 5.56x45mm) plus eight loaded magazines at nearly two pounds each. The AR is lighter (even with RRA's heavier-than-average barrel profile), the ammo is lighter, the magazines are lighter.
I would make sure I had a small squeeze bottle of Mobil 1 and some spare batteries for the light and optic (if necessary).
