About this Upper: This upper AR-15 receiver features a standard 'Mil-Spec' design made out of Billet 6061-T6 Aircraft Grade Aluminum. With a Standard rifle cartridge size ejection door. Made by Aero Precision.
Material: 6061-T6 Aluminum - 6061-T6 Aluminum resembles the strength of the more common 7075-T6 aluminum found on original AR-15/M4 pattern rifles. 6061-T6 has excellent strength and workability and was adopted for use in the commercial AR-15 market as it showed high strength and corrosion resistance during firearms testing.
Style: Commercial - 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.
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.
