its actually marked .308, 7.62x51... atleast mine were...


ive had a couple time issues firing x51 NATO rounds out of .308 SA's, sometimes they dont cycle, depending on origin of said shells, age, ect...

if its marked .308, run .308 out of it... running sh!t milsurp ammo out of .308 guns is like running Arco regular gas in your Lambo....

yeah it may work, but its not going to do what its capable of...
