Well I've dumped about 1K rounds through two of 'em so far. No issues at all (surprise huh?).
It seems like they're easier to seat on a closed bolt with 30 rounds and I like the over-insertion tab. I occasionally get a little carried away with mag changes..
I like 'em and I'm usually adverse to change, but I just sold all my usin' mags (M2 pmags and NHMTGs) and will run these exclusively for the foreseeable future.
I don't plan on attending any normal type classes this year, so I don't need a bunch of mags to keep up with everyone so I'm gonna use the two I started with just to get as many rounds as I can through each one.
They will stay fully loaded 24/7 without the covers in place. The covers don't snap to the bottom of the mag anymore and I'm not trying to keep up with 'em...
