Building an AR-15 from the ground up? The Aero Precision M4E1 Lower Parts Kit with MOE SL Grip is the smart way to populate your lower receiver without overpaying for a trigger you don't want. This kit includes all the essential components—takedown pins, springs, detents, bolt catch assembly, magazine catch, safety selector, and buffer hardware—needed to complete an Aero Precision M4E1 lower or any mil-spec lower receiver. The Magpul MOE SL Grip in black provides a comfortable, modular platform that lets you swap ergonomics later if your needs change. Because this kit ships without a fire control group, you're free to drop in your choice of upgrade trigger, whether that's a precision match trigger for distance shooting or a crisp combat-style group for duty or hunting.
Aero Precision's reputation for attention to detail shows in how they've engineered these kits. Every component is present and accounted for—no mystery gaps when you start assembly. The MOE SL grip is a proven Magpul design that works equally well for hunters, competition shooters, and tactical users. The kit is specifically designed for M4E1 lowers, which means no trigger guard component is included since that feature is already integral to the receiver itself.
Whether you're assembling your first AR platform rifle or building a dedicated hunting or range gun, this lower parts kit gets you to the firing-pin-stage with quality components and room to invest in the trigger that matches your shooting style and budget.
| Manufacturer | Aero Precision |
| Product Type | AR-15 Lower Parts Kit |
| Grip | Magpul MOE SL, Black |
| Fire Control Group | Not included (minus FCG) |
| Compatibility | Aero Precision M4E1 Lower, mil-spec AR-15 lowers |
| Included Components | Takedown pins, pivot pin, detents, springs, bolt catch assembly, magazine catch assembly, safety selector assembly, buffer hardware, set screw |
The kit includes all internal parts needed to complete an AR-15 lower receiver assembly except the fire control group (trigger and hammer). It has takedown and pivot pins, all detents and springs, bolt catch, magazine catch, safety selector, buffer retainer, and a Magpul MOE SL grip. There is no trigger guard component because the M4E1 lower receiver has one built in.
Yes. While this kit is designed specifically for Aero Precision M4E1 lowers, the components are mil-spec compatible and will work with any standard AR-15 lower receiver. The only exception is the integrated trigger guard on M4E1 receivers—if you use a different lower that has a separate trigger guard, you'll need to source that separately.
This is the "minus FCG" variant, which lets you choose and install your own trigger upgrade. If you want a mil-spec trigger included, Aero Precision also offers versions with standard fire control groups already installed.
Yes. The Magpul MOE SL grip uses a standard grip screw and can be swapped for any other mil-spec AR grip if you want to change ergonomics later.
