I recently bought several of these from buds, and they top notch, well built, steel locking lugs, steel feed lips, and polymere body

With US palm mags make sure they don't have "-R" at the end of the model number or this means they are range mags and don't have the steel reinforcements which will make them less durable

Found the magpul m2 in stock here

I also have one of these, but it is a pain to load the cartridges into the magazine, it fits well in the rifle and functiona has been 100% reliable but the bullets need pushed back several times while loading it.

I also have some Zastava manufacturers polymere mags these

-------------------
I've had zero failures with those as well.
Zastava also makes steel magazines, which were out of stock when I ordered my polymere mags so I haven't tried them.

I also have some magpul mags (Gen m2 and m3) the most have steel lugs the m2 have plastic, the M3 are a tight fit at 1st but will break in after inserting and removing them several times, the m2 fit right away but aren't as durable
M3 are in stock here
