Will mk2 mags work in a mk1?
Will mk3 mags work in a mk1?

I don't think so. That's why they market different mags for each. I could go find out, because I happen to have a Mk I downstairs... I mean, I can't shoot it, but I'll see if the Mk II magazine functions.

The Mk II magazine sits considerably higher. Cycling by hand, it seemed to interfere with ejection, because the rounds barely dribbled out when I pulled the bolt to the rear.

MK I and II are heel release and MK III is side release

MK I and II are heel release

Correct, but they are not interchangeable.
