Aero M5 Ar10 Stripped Lwr Blk

The Aero Precision M5 AR-10 Stripped Lower Receiver in .308 Winchester/7.62 NATO is a precision-machined foundation for building a full-power rifle platform. As a stripped lower—the legally regulated firearm component—it arrives unassembled and ready for the builder who wants complete control over their .308 platform. The M5 line represents Aero Precision's scaled-up engineering for large-frame AR systems, offering the dimensional accuracy and surface finish quality that operators and serious builders expect.

The receiver features an anodized black finish—a military-standard hard-coat anodize that resists corrosion and wear in field conditions while maintaining a professional aesthetic. At 0.94 lbs, the receiver contributes minimal weight to your final build, allowing component choices to drive the balance and handling characteristics of your rifle. The M5 pattern is the industry standard for large-frame AR builds; it maintains compatibility with standard .308 AR upper receivers and most aftermarket furniture designed for the platform. Stripped configuration means no fire control group, no safety selector, no stock or buffer tube—you select and install every component, ensuring your build meets your exact specifications and handling preferences.

This receiver is the choice for gunbuilders constructing precision rifle systems, law enforcement designated marksman rifles, hunting platforms, or long-range training rifles. Because you control the parts list entirely, you can optimize for caliber versatility (.308 Winchester and 7.62 NATO share the same magazine and chamber dimensions), trigger feel, ergonomic layout, and intended use. Whether you're building a sub-MOA target rifle, a duty rifle, or a multipurpose field gun, starting with a quality stripped lower from a manufacturer known for tight tolerances and consistent finishing gives you a reliable platform to work from.

Aero Precision M5 uppers, handguards, and compatible M5 parts are readily available, making this a sensible choice if you plan to scale your .308 inventory or want to maintain a consistent platform family. Federal law requires that a licensed dealer transfer this item and conduct background screening. Ensure you comply with all local and federal regulations regarding lower receiver ownership and assembly before purchase.
