So basically what you're saying is that DPMS (not surprisingly) have a disclaimer on their site saying shoot .308 in .308 rifles and shoot 7.62x51mm in 7.62 Nato rifles... And Ruger puts "caution guns are dangerous" barrel stamps on all of it's guns, and McDonald's put's "Caution: Contents are HOT!" on it's coffee cups and lids...

What their lawyers allow them to say and what is real are not necessarily the same thing...
