Aero Precision M5 308 Stripped Lower – Special Edition: Texas- Anodized Black

Product Description

The Aero Precision M5 308 Stripped Lower – Special Edition: Texas is a serialized lower receiver designed for .308 Winchester and 7.62x51mm AR-style rifle builds. This Texas edition features an anodized black finish and Aero Precision’s state-themed rollmark.

A stripped lower gives you full control over your trigger, buffer system, and stock selection. It’s the ideal starting point for a custom large-frame AR build.

This is a serialized firearm component and requires FFL transfer. Because it ships without internal parts or a stock, you’ll select every component that determines the finished rifle’s trigger pull, weight, and ergonomics.

What Makes the Aero M5 Lower Different

The M5 platform is Aero Precision’s large-frame AR system, sized for .308 Winchester cartridges. It sits between the smaller AR-15 footprint and heavier SR-25 variants. The M5 lower receiver uses a proprietary dimension set, so you’ll pair it with an M5 upper receiver and components designed for Aero’s large-frame pattern.

The Texas special edition rollmark is cosmetic, not structural. The forging, machining, and mil-spec dimensions remain the same as Aero’s standard M5 lower receivers. If you’re building a rifle in Texas or want the state mark, this is the version. If the rollmark doesn’t matter, a standard M5 lower functions identically.

Building on an Aero M5 Stripped Lower

A stripped lower arrives without a lower parts kit, trigger assembly, buffer tube, or stock. You source those separately. That means you choose the trigger weight, single-stage or two-stage design, carbine or rifle buffer system, and stock length of pull.

The M5 accepts standard AR-style pistol grips and most aftermarket triggers designed for large-frame lowers. Because this is a serialized receiver, it’s the only component in your build that requires FFL transfer.

Barrel length, handguard type, and gas system configuration are determined by the upper receiver assembly, not the lower. The lower sets the foundation for ergonomics and control.

Frequently Asked Questions

Q: Will the Aero M5 Texas lower work with standard AR-15 uppers?

A: No, the Aero M5 lower requires an M5 upper receiver. The M5 is a large-frame platform sized for .308 cartridges and uses different pin spacing and dimensional specs than AR-15 lowers. You need an Aero M5 or compatible .308 upper designed for the M5 footprint.

Q: What is the difference between the Aero M5 stripped lower and a complete lower?

A: A stripped lower is just the serialized aluminum receiver with no internal parts. A complete lower has the trigger assembly, lower parts kit, buffer tube, buffer, spring, and stock already installed. Buying stripped gives you full control over each of those components.

Q: Does the Aero Precision Texas edition lower have any functional differences?

A: No, the Texas edition differs only in the rollmark engraving on the magwell. The forging, machining tolerances, and compatibility are identical to Aero’s standard M5 stripped lower receivers. It’s a cosmetic variant.

Q: Can I use this lower for a pistol or SBR build?

A: Yes, the M5 lower can be configured as a rifle, pistol, or registered short-barreled rifle depending on the parts you install and the applicable ATF regulations. If you’re building an SBR, you’ll need an approved ATF Form 1 before assembly. Send us a message if you need guidance on NFA builds.

Q: How do I transfer a stripped lower receiver in Texas?

A: A stripped lower is a serialized firearm and requires FFL transfer. You’ll complete a Form 4473 background check at Western Sport when you pick it up. Bring a current Texas driver’s license or state ID and be prepared for the standard NICS check. The process typically takes minutes unless the background check is delayed.

Q: What lower parts kit and buffer system does the Aero M5 lower require?

A: The M5 lower uses large-frame lower parts kits and .308 AR buffer systems, not AR-15 components. Specific part numbers and compatibility vary by manufacturer. Send us a message to confirm which kits work with the M5 platform before you order parts separately.
