Aero Precision M5 308 Stripped Receiver Set – Anodized Black

Product Description

The Aero Precision M5 308 stripped receiver set is a matched upper and lower receiver pair designed for .308 Winchester AR-platform builds. This set features an anodized black finish and provides the serialized foundation for a custom rifle chambered in .308 or 7.62×51 NATO.

Stripped receivers give you complete control over parts selection, trigger group, handguard, and barrel configuration. The M5 platform is built around the larger .308 cartridge, requiring different dimensions and reinforcement compared to standard AR-15 receivers.

Because this is a stripped set, you select every component that goes into the build. That level of customization appeals to shooters who want specific triggers, stocks, or barrel profiles that factory rifles do not offer.

What a Stripped Receiver Set Means for Your Build

A stripped receiver set contains no fire control group, no bolt carrier group, no barrel, and no furniture. You are buying the two aluminum forgings that form the serialized core of the rifle. Everything else must be sourced separately.

This approach lets you choose a match-grade barrel, a competition trigger, or a specific stock without paying for factory parts you will replace. It also means you need to understand .308 AR parts compatibility and have the tools or gunsmith access to complete the assembly.

The lower receiver is the serialized component and requires an FFL transfer. The upper receiver is not serialized under federal law but is sold as part of this matched set.

M5 Platform and .308 AR Compatibility

The Aero Precision M5 uses DPMS Gen 1 .308 pattern specifications, which is the most common standard for .308 AR rifles. Most aftermarket .308 AR parts are designed around this pattern, but not all manufacturers use identical dimensions.

Before purchasing barrels, handguards, or bolt carrier groups, confirm they are specified for DPMS Gen 1 or Aero M5 compatibility. Some manufacturers produce proprietary .308 patterns that will not fit without modification.

Frequently Asked Questions

Q: Is the Aero Precision M5 308 stripped receiver set compatible with AR-15 parts?

A: No, the M5 308 receiver set is not compatible with standard AR-15 parts. The .308 platform requires larger dimensions for the magazine well, bolt carrier group, barrel extension, and buffer system. You must use .308 AR or DPMS Gen 1 pattern components.

Q: What is the finish on this Aero M5 receiver set?

A: The finish is anodized black. Anodizing creates a hard, corrosion-resistant surface on the aluminum and is the standard finish for most AR receivers.

Q: Can I build this receiver set into a rifle chambered in 6.5 Creedmoor?

A: Yes, the M5 platform accepts multiple cartridges that share the .308 case head, including 6.5 Creedmoor, .243 Winchester, and .260 Remington. You will need a barrel, bolt, and magazine specific to your chosen cartridge.

Q: Do I need an FFL transfer to buy the Aero M5 stripped receiver set?

A: Yes, the lower receiver is serialized and requires an FFL transfer. Western Sport is a licensed FFL dealer, and we can complete the transfer on site or ship to your local FFL if you are outside our area.

Q: How does the Aero M5 compare to other .308 AR receiver sets?

A: The Aero M5 follows DPMS Gen 1 specifications, which makes it compatible with the widest range of aftermarket .308 AR parts. Some manufacturers use proprietary patterns that limit parts choices. The anodized finish is durable and standard for this category.
