Nothing. Redditors who can't think for themselves and have no real world experience will cite an influencer who says something's bad. That's what this is.

If you drop a full Lancer magazine, uncovered, it's more likely than a Magpul magazine to spit out a couple rounds. That's just demonstrably true.

It won't cause malfunctions

As cynically as you prefer to think about every besides yourself, in my case, I turned on Lancer mags pretty quickly when dropping them in the desert out here in Utah regularly resulted in stuck followers -- and not the kind stuck you just tap a few times to fix, but totally locked up magazines that necessitate taking the mag completely apart.

These things are allergic to the tiniest bit of moon dust that Pmags and GI mags churn right on through. They do cause malfunctions. I've seen it multiple times, to the point my Lancers don't see ammo or the range day anymore. It doesn't have fuck all to do with influencers and/or not being able to think for myself.

I know it's easy to pretend like you're outside and above it all and to condescend to everyone, but ironically, it sounds like you're the one who doesn't have any real world experience with the type(s) of conditions that cause these things to fail.
