Davidson Defense Stripped Upper with M4 Feedramps - 7075 T6 Aluminum

Material: 7075-T6 Aluminum - 7075-T6 Aluminum is a high-strength alloy metal with great ductility, toughness, and resistance against fatigue. 7075-T6 was standardized for use in Aerospace equipment and aircraft. The Suffix T6 is a temperament treatment to increase the overall toughness and strength of the Aluminum. 7075-T6 Aluminum was chosen for the AR-15 platform for its ease of manufacturing, lightweight properties, and strength.
Style: Mil-Spec - Mil-Spec is the standard for the United States Military for reliability, commonality, reduced cost, and meeting the requirements of a service rifle. 'Mil-Spec' is the essential technical requirement for military-unique materiel or substantially modified commercial items.
