M16A2 is the select-fire US Army rifle...unless they've all transitioned to the M4, but I don't think that's the case. I used the M16A2 and M249 until I got out in late 2005.rotor wrote:It is my understanding that in the military it is expected that an AR15 (whatever the military version is ) must be sighted in with no more than 15 rounds. Mine was dead on right out of the box. I too would like to be an "expert" using your ammo.
