 It is marked "ArmaLite", and has a quick-detachable, see-through mount that attaches to an integral dovetail spot-welded to the top of the receiver.The mount could also feasibly be used with other scopes if they had a 1-inch diameter tube.The ArmaLite brand was purchased in 1996 by Eagle Arms, a U.S. small arms manufacturer, who adopted the ArmaLite brand for their company.
