Davidson Defense AR-15 Stripped Upper Receiver - .458 SOCOM/.450 Bushmaster/.45 ACP
Upper Receivers mount and house the barrel, handguard, and gas system in a AR-15 or LR-308/AR-10. Mil-Spec upper receivers are made to 'Military Specification' and are meant to either match or exceed the military requirements imposed onto the design for its service rifles. Mil-Spec Enhanced upper receivers feature all of the qualities of a 'Mil-Spec' upper receiver and incorporate various minor cosmetic, and design changes, externally, while retaining all of the features and functionality of a standard Mil-Spec upper receiver.
About this Upper: This upper AR-15 receiver features a standard 'Mil-Spec' design made out of Forged 7075-T6 Aircraft Grade Aluminum. Big-Bore rifle cartridge size ejection door.

Material: Forged 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 Enhanced - Mil-Spec Enhanced is a further modification of standardized Mil-Spec parts, this would mean that the specific part meets the essential technical requirements for the US Military, but has been modified for commercial use.
Finish: Anodized - This upper receiver is anodized, this process increases the thickness and hardness of the natural oxide layer on the surface of the metal parts. This increases the corrosion and wear resistance of the Upper Receiver.
