This version of the ACE is designed specifically for use on any universal 1-inch flashlight gunmount.  The brass insert inside the tube has been removed, allowing the light body a smaller diameter.  The circuitry is the same circuit in the classic ACE.  However, the reflector has been optimized to remove the "donut" pattern in the hotspot.  The extension tube matches the default body style and ergonomics.
