Overview
Built around Aero Precision’s M5E1 platform, this assembled upper receiver is intended for .308 Winchester builds that call for a free-floated handguard setup with a streamlined mounting system. Its one-piece design integrates the handguard mounting platform with the upper receiver, using a reduced screw count and an included barrel nut for installation. The Kodiak Brown finish gives the assembly a distinct look while the platform’s design emphasizes a solid, purpose-built foundation for a hunting or field rifle build. Because it is sold without a barrel, it is best suited to shooters assembling a custom upper around their preferred barrel choice.

Considerations & Trade-offs
- This is an upper receiver only and does not include a barrel, so it requires additional components before it can be used as a complete setup.
- The M5E1 design is specific to the platform, so compatibility should be confirmed with the rest of the build before purchase.
- Installation is described as straightforward, but it still depends on correctly fitting the barrel assembly and using the included barrel nut.
- The one-piece upper/handguard mounting design may simplify assembly, but it also means the receiver is tied to this specific mounting approach rather than a more modular layout.
