Yeah, well, they've been totally problem free in various competitions, with various rifles, and various ammo including Wolf and Silver Bear steel-cased. They aren't reputed to have any issues, even rarely, the way that Lancer and Tangodown ARC mags are (both of which have worked for me about 98% of the time, but not 100 - the Lancer AWM is too tight in some magwells, and the gen1 ARC has jamming issues if you use it in an upper WITHOUT M4 feedramps). I like the fish scales and slim, no-snag design. I just can't find anything to dislike, although I suspect the Pmags will be more durable with their bulkier design and dust cover to protect the feedlips.
