there are a few mags coming back in stock recently.
JSE has had a few 9mm & 7.62x39 mags back in stock , and copes has had the D&H back in stock for nearly retail price. copes had a few tapco mags for $13- a sort of normal price --
you can still back order mags for nearly retail price at several places.
CDNN and SARCO have had AR mags for $20-$29 --that charles daily 40 round mag @ cdnn for $29 ain't that far off really-- i think it is a either CMMG or C_products/ASC--
the 40 round mags were all ways quite a bit more $ than a 30 rounder --
mags are coming back on the market for more reasonable prices --a few at a time.
haven't followed AK mags much, i expect their pricing will be about the same.
i don't know about these guys paying a $100 for one mag-- obviously the politics of the day and panic buyers are going to push prices up quite a bit.
they must not be looking for a better price is all i can say.
i figure standard 30rd size mags will sort of stabilize around $20-$30 for the good ones.
production ramps up and money goes down as people buy what they can afford so sales start to taper off some.
