The 5D is strong, rugged and dependable. The blue- black anodizing produces a long lasting no rust finish. The alloy used to manufacture this sight has a tensile strength of 85,000 pounds. Yet, the FP is light and compact weighing only 1 1/2 ounces. Many rifles are now being drilled and tapped at the factory for installation of the FP.
