Make sure they work
YMMV.
The 25 rounds mags have proven to be less reliable than the 20 round magazines. I had a few go arounds with S/A, and then CMI to
shake the bugs out of the bad magazines I got ( from a vendor many here would know ).
Out of 6 magazinesI've sent 3 back, got replacements, and 2 more have to go back. None have more than 750 rounds through them.
Yours could work perfectly, about half mine did. I only have 2 left that repeatedly cause issues, but the 20 rounders just plain work. CMI has stood behind the magazines FWIW, but... Identifying bad magazines is work, not fun and it costs money, ammo & time that I'd really rather be practicing marksmanship with, not how to clear malfunctions. I prefer to do that on my own time, not some vendor's time.
My CMI mags would fail with DAG surplus, Serbian PPU, Federal 150 grain fmj, and they -would- have failed with reloads if I were inclined to reload.
