Thread: Best Plastic AR mags

Only polymer mags I've used are the Diemaco ones issued with C7's and Magpul PMags. I used to use steel H&K mags but started to have an occasional issue so switched to Magpul's and haven't had a problem since (the HK mags had seen a reasonable amount of use though). You can't seat the bullets out as far in the PMags as the metal mags, as the mag walls are thicker but not really an issue.
