Uh, a couple of cases of ammo? I always wonder why people are so quick to spend thousands on accessories and only shoot a few dozen rounds through the gun.
Avoid commercial .308 ammo. Stick to 7.62 NATO ammo. Portugese and DAG are some of the best currently available NATO spec ammo available now.
In life, strive to take the high road....It offers a better field of fire.
