Aero Precision APAR308505AC Assembled Receiver 308 Win 7075-T6 Aluminum Flat Dark Earth Cerakote Receiver for M5 Platform

The Aero Precision APAR308505AC Assembled Receiver for the M5 platform chambered in .308 Winchester delivers precision-engineered construction built on a foundation of 7075-T6 aluminum—the same aerospace-grade material used in tactical and military platforms where weight savings and structural integrity cannot be compromised. This fully assembled receiver arrives ready for integration into your build, eliminating the guesswork of component machining and ensuring dimensional consistency from the factory. The Flat Dark Earth Cerakote finish provides both corrosion resistance and a non-reflective matte appearance critical for field operations where glint discipline matters.

The 7075-T6 aluminum specification is significant: this T6 heat-treatment maximizes hardness and rigidity, critical for maintaining tight tolerances in a large-frame platform like the M5 that must handle the recoil impulse and chamber pressures of .308 Winchester ammunition. The Cerakote application goes beyond aesthetics—it bonds at the molecular level, offering superior adhesion compared to paint or standard anodizing, and maintains finish integrity in harsh environments including salt air, moisture, and thermal cycling. At 1.1 pounds, this receiver provides the weight distribution expected of a quality large-frame platform without unnecessary bulk.

This assembled receiver is designed for operators and precision shooters building semi-automatic rifle configurations on the M5 platform—a popular choice for long-range target work, precision rifle competitions, and precision applications requiring the ballistic performance of .308 Winchester. Whether upgrading an existing build with a fresh receiver or starting a new platform, this component eliminates a critical manufacturing step while guaranteeing the dimensional accuracy required for reliable function. The receiver serves as the firearm's serialized foundation, and Aero Precision's reputation for tight tolerances makes this component a dependable baseline for any M5 .308 build.
