Sorry, I didn't word that very well, but that was my point. I've heard very mixed reviews on what you can and cannot use in one of these. Hornady clearly advertises it's made for cleaning upper receiver groups and small parts, but then the vast "wisdom" of the internet seems to claim you can't dump your lower in it, or it will dissolve into fairy dust or something. I shoot a lot suppressed, and the idea that I could disassemble the gun and drop it in a tank, dirty mags and all, is really appealing. But not if it's going to somehow mess with the anodizing or something.

Would really like to hear from someone who has dunked their AR a few dozen times.
