Ruger's M16 Alternative: the Select-Fire AC-556
The Ruger AC-556 is a select-fire variant of the Mini-14, designed to compete with the M16 for military and police contracts. It features a three-position selector for semi-auto, 3-round burst, and full-auto fire, with a non-resetting burst mechanism. While it didn't secure major US military contracts, it found use with some police agencies and international clients, and remains a collectible transferable machine gun.
