OP UPDATE: Issue Resolved
So... I took a flat file to the bottom of the lug that's welded on the aft end of the magazine. I went slow and checked the fit after about every 5 passes or so. Eventually, I got both Pro Mags to the point where they will positively and consistently lock into the rifle, and with no apparent negative side effects or unintended consequences (knock on wood).
I have not yet tested with loaded mags, or live fired. Next time I'm at the range with this rifle, I'll do so and report back here ONLY if there are problems.
Still... I wouldn't recommend Pro Mags to anyone, but I suppose the silver lining is that they appear to be salvageable if you do end up with one.
Oh. After looking at them for a while, they're a glossy black that just doesn't look right (or good) to my eye.
