The Aero Precision M4E1 Complete Lower Receiver with FDE Magpul MOE furniture is a ready-to-run lower that lets you skip the assembly headache and get straight to building your AR-15. This complete lower receiver arrives fully assembled with all the fire control group, trigger guard, and safety components installed—meaning you're one upper away from a functional rifle. For builders who want a solid foundation without the guesswork, the M4E1 platform from Aero delivers the precision tolerances and clean design you expect from a premium AR manufacturer.
What sets this complete lower apart is the included FDE Magpul MOE stock, a drop-in buttstock designed for standard AR-15/M4 mil-spec carbine buffer tubes. The MOE platform is trusted by shooters across all disciplines for its ergonomics and reliability. The FDE (Flat Dark Earth) finish pairs with Aero's refined lower receiver design, giving your build a cohesive, field-ready look right out of the box. Whether you're assembling a hunting rifle, patrol carbine, or precision trainer, starting with a complete, fully-assembled lower eliminates potential assembly errors and gets you to the range faster.
Aero Precision has built a reputation for attention to detail in manufacturing, and this M4E1 lower reflects that commitment. The design is clean, the tolerances are tight, and everything functions as intended from day one. If you're shopping for a complete lower for your next AR build, this unit handles the critical assembly work so you can focus on choosing the upper and optics that match your mission.
| Brand | Aero Precision |
| Product Type | Complete Lower Receiver |
| Model | M4E1 |
| Stock | Magpul MOE Carbine |
| Stock Color | FDE (Flat Dark Earth) |
| Compatibility | AR-15/M4 mil-spec carbine buffer tubes |
| Assembly Status | Fully assembled |
A complete lower comes fully assembled with all internal fire control components, hammer, trigger, safety selector, and trigger guard already installed. A stripped lower requires you to assemble these parts yourself. With the M4E1 complete lower, you skip that assembly work and go straight to mating it with an upper receiver and buffer tube system.
Yes. The M4E1 lower is designed to work with any AR-15 upper receiver that accepts a standard mil-spec lower receiver interface.
The Magpul MOE stock included with this lower is a drop-in for standard AR-15/M4 mil-spec carbine buffer tubes. You'll need to pair this complete lower with a carbine buffer tube, spring, and buffer to complete your rifle.
A complete lower is the regulated, registered part of an AR-15 that comes ready to use—no additional gunsmithing or internal assembly needed. With the M4E1 here, you're buying a finished, tested component that arrives ready to function. You'll still need an upper receiver, barrel, handguard, and bolt carrier group to complete the build.
