Eclipse Ultra IIslide and frame are made from stainless steel. After final machining they are finished in durable matte black oxide, then all flat surfaces are brush-polished. This leaves inset and curved surfaces matte black and gives the dynamic finish that lends them their name. To further compliment the look they are fitted with black small parts and a set of gray/black laminated grips checkered in the classic double diamond pattern. The Eclipse ultra II has a 30 LPI checkered front strap for a more secure grip, a Premium Aluminum Trigger and Meprolight Tritium night sights – all from the Custom Shop.LOWER 48. USA ONLY.
