I almost feel ashamed for asking, but times being what they are...
Mako Group has started importing some new Israeli steel AR mags. They're running a special right now that makes the mags about $17 each, shipped, after discount codes.

While I harbor no illusions that they will be as good as PMags or good-quality GI mags, I'm wondering if they're worth buying just to have some range mags, since nobody seems to have PMags, Lancers, ARC mags or GI mags in stock right now.
