Behind the scenes
The AC-556 is a selective-fire version of the Mini-14 marketed for military and law enforcement use. The design incorporates a selector on the right/rear of the receiver to select either semi-automatic, 3-round burst, or full-automatic fire modes; the manual safety at the front of the trigger guard operates the same as a standard Mini-14.
