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 miltary 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.
Brand: Aero Precisionâ€™s roots are deeply tied to aerospace, and their drive for clean, perfect engineering and machining stems from that. When youâ€™re building something that will fly in the air, there is no margin for error. Aero Precision takes that same approach in the firearms industry. Not every manufacturer will have razor thin tolerance levels. Not every manufacturer will personally oversee the development, design, and machining of every part that comes off the line. Aero Precision is not every manufacturer.

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.
