My brother-in-law is all in for 5.56, and he killed a lot of Muzzies in Bush’s wars. You know what they say about brother-in-laws? Well, I don’t either, but he seems to know what he’s talking about.
I’m not saying they don’t work, I’m simply saying 7.62mm is far superior and I have ten years and three tours so I also know what I’m about.
