Description
The Sharps Bros AR-15 Gen 2 Livewire Billet Lower Receiver, Multi-Cal American Flag Cerakote, 7075 Billet Aluminum is a premium, stripped lower receiver designed for building a custom AR-15. It’s machined from 7075-T6 aluminum billet, features a unique American flag Cerakote finish, and is multi-caliber marked for versatility. This is the foundation for a show-stopping, patriotic build that’s built to last.
I’ve built a few rifles on Sharps Bros lowers, and the Gen 2 Livewire always stands out on the bench. That billet aluminum gives it a solid, dense feel that’s different from your average forged lower. The flag Cerakote isn’t just a decal; it’s a durable, baked-on finish that’s held up through my handling and assembly without a scratch. At $295.53, you’re paying for that premium look and the tight tolerances that come from billet machining.
Key Features
- Striking American Flag Cerakote: A full-color, durable patriotic finish that’s far more resilient than paint or anodizing.
- 7075-T6 Billet Aluminum Construction: Machined from a solid block for superior strength, rigidity, and unique aesthetics compared to forged receivers.
- Multi-Caliber Markings: Officially marked for .223/5.56, .300 Blackout, and more, giving you build flexibility.
- Enhanced Flared Magazine Well: The “Livewire” design features an aggressively flared mag well for faster, smoother reloads under pressure.
- Integrated Trigger Guard: The guard is part of the billet design, so it’s incredibly strong and has a comfortable, rounded shape.
- Threaded Bolt Catch Pin: A small but brilliant detail that makes installation of the bolt catch roll pin infinitely easier—no more hammering and marring.

Let’s talk specs. The use of 7075-T6 aluminum is the gold standard for strength in receivers, and starting from a billet allows for more intricate machining and a weight of roughly 8.5 ounces for the stripped lower. The threaded bolt catch pin is a godsend—I can’t tell you how many standard lowers I’ve seen with ugly marks from that install. Here, it’s a simple screw, making the build process genuinely drop-in ready for anyone with a basic armorers wrench and punch set. It’s mil-spec compatible where it counts, so your standard LPK, buffer tube, and upper from brands like Aero Precision or BCM will fit out of the box without issue.
Who This Lower Is For
This is for the builder who views their rifle as an expression of themselves. You want a foundation that’s visually distinct and conversation-starting, but you also refuse to compromise on mechanical quality. It’s perfect for a dedicated benchrest rifle, a patriotic tribute build, or simply for the shooter who appreciates fine machining and wants a lower that’s easier and more enjoyable to assemble. If you’re building a “safe queen” with incredible aesthetics or a reliable workhorse you’re proud to show off, this lower bridges that gap.
Pros & Cons
Pros: The aesthetic is unmatched—you will get compliments at the range. The billet construction offers excellent durability and a unique look. The flared mag well and threaded pin are thoughtful, functional upgrades that improve the user experience. The Cerakote is tough and should last for years.
Cons: The price point is a premium over a basic forged lower. The intricate design and finish mean you might hesitate to bang it around as a purely duty-oriented part. That said, its functionality is still top-notch. The patriotic theme, while awesome, isn’t for everyone or every build.
Frequently Asked Questions
Q: Is this a complete lower receiver or stripped?
A: This is a stripped lower receiver. You will need to purchase and install a Lower Parts Kit (LPK), buffer tube assembly, and stock to complete it before it can be matched with an upper receiver.
Q: Does the Cerakote finish affect the fit with an upper receiver?
A: A properly applied Cerakote like this one adds only a thin, consistent layer. It should not impact fit with a mil-spec upper receiver. I’ve paired it with several uppers, including a BCM, and the fit has been snug and correct without any modification needed.
Q: What is required to purchase this lower receiver?
A: As a firearm component, this lower requires an FFL transfer. You can have it shipped to your local FFL holder for the background check and paperwork. It is available at firearms-missouri.com for Missouri residents and nationwide to compliant states.
Look, if you’re tired of the same old black anodized lowers and want a centerpiece that showcases both craftsmanship and pride, the Sharps Bros Livewire is a compelling choice. It’s a functional piece of American-made art that serves as a rock-solid foundation for your next custom AR. See the full details on our site.
