AeroPrecision
Building an AR-308 from the ground up demands quality components you can trust, and the Aero Precision M5 Lower Parts Kit with MOE SL Grip is engineered to give you exactly that. This FDE kit bundles all the internal components and controls needed to complete an M5 lower receiver—the serialized, regulated part of your rifle. Whether you're assembling your first large-frame AR or adding to a collection, this kit eliminates the guesswork of sourcing individual parts and ensures compatibility with Aero Precision's M5 platform.
The M5 is Aero Precision's answer to shooters who demand a .308 rifle built to the same standards as the AR-15 platform. This lower parts kit includes everything specific to M5 geometry: takedown pins, pivot pin, bolt catch, and an extended magazine catch button sized for larger, heavier rounds. The Magpul MOE SL grip—known for its slim profile and ergonomic angle—ships in FDE (Flat Dark Earth) to match modern rifle aesthetics. The kit also bundles a standard mil-spec fire control group with hammer, trigger, disconnector, and all springs and detents, so you're not buying extras or hunting for oddball components.
Aero Precision has built a reputation for tight tolerances and attention to detail, and this kit reflects that. The components are compatible only with M5 lowers (not M4 or other platforms), so verify your lower before ordering. Assembly doesn't require gunsmithing, but familiarity with lower assembly is assumed. If you're stepping up to .308 or building a second rifle, this kit streamlines the process and pairs well with a quality upper and barrel for a hard-hitting, reliable rifle.
| Brand | Aero Precision |
| Platform | M5 (.308) |
| Grip | Magpul MOE SL |
| Grip Color | FDE (Flat Dark Earth) |
| Fire Control Group | Mil-spec hammer and trigger |
| Included Components | Takedown pin and spring, pivot pin and detent, bolt catch assembly, magazine catch, safety selector, trigger and hammer assemblies, disconnector, buffer retainer, all springs and pins |
No. This is an M5-specific kit designed for Aero Precision M5 lower receivers (.308 platform). M5 components will not fit standard AR-15 (5.56) lowers. Verify your lower before purchasing.
The kit contains all internal lower components: M5-specific takedown pin, pivot pin, bolt catch, extended magazine catch button, safety selector, fire control group (hammer, trigger, springs, disconnector), detents, buffer retainer, roll pins, and the Magpul MOE SL grip in FDE. No tools or adhesives are included.
Yes. The kit ships with a standard mil-spec hammer and trigger, but the lower is drilled to accept aftermarket drop-in or competition triggers designed for the M5 platform. You would replace the hammer and trigger assembly with your preferred upgrade.
No special licensing is required, but lower assembly assumes mechanical familiarity with AR-platform rifles. If you're new to assembly, reference materials and videos are widely available, or consult a local gunsmith or range armorer for hands-on guidance.
