Aero Precision APAR611310AC Assembled XL Receiver 7075-T6 Aluminum Black Anodized Receiver for AR-15

The Aero Precision APAR611310AC Assembled XL Receiver is a precision-machined, fully assembled upper receiver built from 7075-T6 aluminum and designed for AR-15 platforms. This receiver serves as the foundation for custom rifle builds, replacement components in existing systems, and precision carbine configurations across law enforcement, military, and civilian tactical applications. Whether you're building a duty rifle, competition platform, or precision long gun, an XL receiver accommodates larger optic mounts and rail systems without the constraints of standard profiles.

Aero Precision's commitment to dimensional accuracy and manufacturing tolerances is evident in the 7075-T6 aluminum alloy selection—a military-grade material that delivers superior strength-to-weight performance compared to standard 6061 alloys. The black hard-coat anodize finish resists corrosion, abrasion, and environmental degradation while maintaining a professional appearance in field conditions. The XL configuration provides enhanced real estate for accessory mounting, allowing shooters to run larger diameter scopes, offset iron sights, and modular rail accessories without rail conflicts—critical considerations for law enforcement duty rifles and precision platforms.

This assembled receiver is ideal for gunsmiths, armory technicians, and experienced builders who require a fully finished upper without assembly labor. It pairs seamlessly with mil-spec or commercial lower receivers, standard AR-15 bolt carriers, and charging handles—ensuring compatibility across platform variations. The compact weight of 0.69 lbs keeps your rifle's overall balance intact, making it suitable for rapid-response configurations where handling speed and target acquisition matter. Installation requires only basic assembly knowledge; the receiver threads directly onto matched lower components with no modifications necessary. For those prioritizing quality over cost-cutting alternatives, Aero Precision receivers represent a reliable, time-tested choice backed by consistent accuracy and durability standards.
