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-engineered, black anodized AR-15 upper receiver designed to serve as the foundation for custom rifle builds. Crafted from 7075-T6 aluminum, this extra-large format receiver delivers the strength and dimensional stability required for reliable firearm assembly while maintaining minimal weight—critical for operators building carbines intended for extended patrol or training cycles. Pre-assembled construction means the receiver arrives ready for component integration, eliminating a labor-intensive step in the build process.

7075-T6 aluminum is a heat-treated alloy specified in aerospace and military small arms applications for its superior strength-to-weight ratio compared to standard 6061 or 7075-T73 variants. The T6 temper designation indicates the material has been solution heat-treated and artificially aged to peak hardness, making it the appropriate choice for upper receivers that must withstand repeated loading cycles and sustained precision demands. Black anodizing provides corrosion resistance and aesthetic consistency with modern tactical finishes. The XL profile accommodates enlarged charging handles and rail systems preferred by shooters using optics-mounted configurations on precision or designated marksman setups.

This receiver suits builders assembling AR-15 platforms for duty use, competition, or long-range training—scenarios where precision component matching and repeatability determine performance. Aero Precision receivers are dimensionally consistent within tight tolerances, ensuring fit with standard mil-spec barrel extensions and bolt carrier groups. The assembled format reduces assembly error and is preferred by operators prioritizing build integrity over component-by-component assembly.

AR-15 upper receivers are regulated as firearm components under federal law; compliance with applicable state and local firearms laws is the purchaser's responsibility. Verify receiver compatibility with your intended barrel extension, charging handle, and rail system before final purchase to confirm seamless fit within your build specification.
