Sorry I wish I had a better answer, man. Pmags have worked flawlessly, everything else is hit or miss mystery meat donated mags. I'm sorry I can't be of more help

I think dpms and Anderson are "good" for ar10s. People say they're harder to build but while mine did fit together like shit, with just a few parts swapped everything was kosher. I did have to file the top of the lower so the charging handle could clear without binding though lmfao

Unfortunately just pmags for now
Most other mags have been wonky in my Anderson lower dpms pattern shit fuck
>picrel is the same receiver combination that works flawlessly in full auto
