Aero Precision M5 Lower Parts Kit W/Moe Grip, No Fcg For Ar-308 Fde

The Aero Precision M5 Lower Parts Kit with MOE Grip in FDE is a purpose-built component set for builders assembling an AR-308 rifle from the ground up. This kit bundles the small parts and hardware you need to complete an Aero M5 lower receiver—minus the fire control group, making it ideal if you're planning to source a premium aftermarket trigger separately. The included Magpul MOE grip in Flat Dark Earth pairs rugged ergonomics with a color that blends on modern rifles, and the M5-specific takedown and pivot pins, bolt catch, and extended magazine catch button are engineered for the larger .308 platform.

Building an AR-308 requires attention to compatibility, and Aero's M5 lower parts are dimensioned specifically for that cartridge class. This kit handles the mechanical essentials—detents, springs, retainers, and selector—so you can focus on sourcing the trigger and completing your build. Whether you're stepping up from the AR-15 or consolidating your parts sourcing with a trusted manufacturer, having a matched lower parts kit from one maker simplifies assembly and ensures proper function on a demanding platform.

FDE (Flat Dark Earth) has become the go-to neutral finish for hunters, competition shooters, and field-oriented builders. If you prefer black hardware, Aero offers the same kit in that finish. This is a no-frills, no-nonsense parts pack: open the box, inventory the pieces, and start your build.

Specifications

Frequently Asked Questions

Is this kit compatible with my AR-15 lower receiver?

No. This is an M5 lower parts kit designed specifically for the AR-308 platform. M5 parts are not interchangeable with standard AR-15 (M4) components. Make sure your lower receiver is marked as M5 or .308 before ordering.

What do I still need to complete my lower receiver?

This kit does not include a fire control group (trigger, hammer, disconnect). You'll need to source a trigger assembly separately—many builders choose this kit specifically because it lets them pair it with an upgraded trigger of their choice.

Is the MOE grip removable, and can I swap it?

Yes, the Magpul MOE grip is removable. If you prefer a different grip later, you can replace it with any grip compatible with the AR-308 platform.

Does this come in black, or only FDE?

This specific kit is FDE. Aero Precision also offers the same M5 lower parts kit with the MOE grip in black if you prefer that finish.
