This comprehensive package provides an ideal starting point, significantly streamlining the build process while ensuring compatibility and top-tier performance from the ground up.

Building a large-caliber AR-style rifle can often seem daunting, involving meticulous parts selection and assembly. However, the Aero Precision M5 Complete Lower Receiver is engineered to simplify this endeavor, offering a pre-assembled, feature-rich base that saves you time and guarantees a consistent, high-quality result. It arrives with essential components expertly installed, allowing you to focus on selecting the perfect upper receiver, barrel, and optics to complete your dream build. Whether your goal is precision target shooting, ethical hunting of medium to large game, or simply owning a powerful and versatile semi-automatic rifle, this complete lower provides the integrity and reliability you demand.

Why Choose the Aero Precision M5 Complete Lower for Your AR-10 Build?

When considering the core of your AR-10, reliability, durability, and ease of assembly are paramount. The Aero Precision M5 Complete Lower Receiver excels in these areas, offering distinct advantages that set it apart from standard lower receivers. It addresses common builder frustrations with intelligent design solutions and comes equipped with premium furniture, making it a truly "complete" solution for your next project.

• Unmatched Quality and Durability: Constructed from forged 7075-T6 aluminum, the M5 lower receiver is built to withstand the rigors of heavy use and harsh environments. This material, combined with a Type III Class 2 hardcoat anodized finish, provides exceptional resistance to wear, corrosion, and abrasion, ensuring your rifle's foundation remains robust for years to come. Forging results in superior grain structure, making the receiver inherently stronger than billet counterparts.
• Streamlined Assembly with Enhanced Features: Aero Precision understands the nuances of rifle building. They've integrated several "builder-friendly" enhancements that simplify the assembly process and improve overall functionality. These include:
  • Threaded Rear Takedown Pin Detent Hole: This ingenious feature eliminates the frustration of dealing with a tiny spring and detent that can easily be lost or bent during assembly. A 4-40 set screw securely retains the detent, making field stripping and maintenance far more convenient and secure.
  • Threaded Bolt Catch Pin: Ditch the notorious roll pin! The M5 lower utilizes a threaded screw pin for the bolt catch, making installation and removal significantly easier and reducing the risk of scratching your receiver or damaging the pin. This small detail reflects Aero Precision's commitment to thoughtful engineering.
  • Integrated Trigger Guard: The trigger guard is a seamless part of the lower receiver's forging, providing increased strength and eliminating the unsightly gap often seen with aftermarket trigger guards. This design enhances aesthetics and ensures robust protection for the trigger assembly.
  • Flared Magazine Well: For rapid and fumble-free magazine changes, the M5 lower features a flared magazine well. This subtle yet effective enhancement guides the magazine into place, crucial during timed events or high-stress situations.
• Premium Pre-Installed Components: This isn't just a stripped lower. The Aero Precision M5 Complete Lower arrives with high-quality components already installed, saving you time and ensuring perfect fitment:
  • Magpul STR Stock: A robust and comfortable collapsible stock featuring an optimized cheek weld and two watertight storage compartments. Its design provides stability and versatility, making it suitable for various shooting positions and body types.
  • Magpul MOE Grip: A classic, ergonomic pistol grip that offers improved comfort and control over standard A2 grips. Its anti-slip texture ensures a secure hold, even in adverse conditions.
  • Lower Parts Kit (LPK): A complete, high-quality lower parts kit is factory-installed, providing all necessary pins, springs, and small components for a functional lower.
  • Receiver Extension (Buffer Tube): A robust Mil-Spec receiver extension is installed, ensuring compatibility with standard AR-10 buffer and spring systems.
  • .308 Carbine Buffer and Spring: The correct buffer and spring for a .308 carbine setup are included and installed, ensuring optimal recoil management and reliable cycling from the start.

Its selector markings are compatible with 45, 60, or 90-degree safety selectors, offering flexibility for user preference.
