Well, yea, but surplus mags are pricey these days.
Every good collection should have a mix of sturdy surplus mags and some inexpensive 'disposable' mags.
AC Unity mags have functioned fine in my WASR, Draco and AK63DS. Mine were the gen 1s with the BHO followers, I swapped in non-bho followers as soon as I got em. They bulge a bit in the middle when full but otherwise run fine. Think I paid $8 a pop but that was a few years ago.
Anyone know if AC Unity changed the floor plate? I read complaints of the floor plates occasionally popping off when dropping a full one on a concrete floor. And that there was some change because of it. I dropped a full one on hard clay ground a half dozen times as a test, no fails.
No experience with the PSA AK mags. Are they rebranded Bulgy mags? If they are, I'd pay a few bucks more a pop for Bulgys every time.
They seem to get good reviews.
Best price I've seen on the Bulgy reinforced poly mags was $15 from CDNN, and they have ACs for $10 as well as metal koreans for $10.
Only mag I can absolutely say 'avoid' is those cheap no name $5 Polish mags that came over a few years ago. Everyone said No Bueno and some dealers started advertising them as '25 rounders' cause the didn't work when full.
