MI. Due to legalities, it's not rigged for folding, but I have the bits for it and if TSHTF I may implement 'em as legalities pale into insignificance in the presence of a credible threat. OTOH, I've gotten pretty good at feeding it from stripper clips and expect to leave it that way, as I find a big mag for .30 Commie unwieldy.
Yeah, I know it's 7.62x39mm, but I like calling it ".30 Commie".
