You’re not just assembling parts; you’re building a rifle. It starts here, with a solid foundation. This is our original, proven forged 80% lower, but we’ve left the final finish entirely up to you. We’re offering it in raw, uncoated 7075-T6 aluminum. This isn’t a blemish or a second. This is a deliberate choice for the builder who demands complete control over the final product.

Think of it as premium lumber for a custom cabinet, or bare metal for a hot rod. This raw lower is your blank canvas. The raw surface is ready to accept any finish you can dream up. Want to apply a durable, professional-grade Cerakote in a specific pattern? The adhesion will be perfect. Planning a meticulous, multi-layer camouflage paint job for hunting? You’re starting from a clean, oil-free slate. Maybe you want to polish it to a mirror shine or try your hand at anodizing. This lower gives you that freedom. You’re not fighting against an existing factory coating; you’re working with the pure material.

Don’t let the raw finish fool you. This is the same tough, mil-spec forged lower we’ve sold for years, just without the final anodizing step. Every other detail remains identical to our standard finished models. It’s machined from a solid forging of 7075-T6 aluminum, the same alloy used in aircraft and military-spec receivers. It’s not a softer 6061 casting. This means it has the superior strength and durability needed for a serious-use firearm.

The magwell is fully broached to ensure smooth, reliable magazine changes every time. The critical fire control group pocket is precisely milled to accept standard AR-15 parts. The “Fire” and “Safe” engravings are already deeply and cleanly marked into the receiver, so that detail is handled for you. The fitment is 100% mil-spec, guaranteed to mate correctly with any standard AR-15 upper receiver. This lower is compatible with 5.56 NATO / .223 Remington, .300 AAC Blackout, 6.5 Grendel, and other cartridges that use a standard AR-15 magazine format.

Who This Is For:

This raw lower is for the hands-on builder. If you take pride in every step of the process and view the finish as a critical part of the build’s identity, this is your part. It’s also a practical choice for anyone who plans to send a batch of lowers out for a professional coating, as many shops prefer to work on bare metal. It eliminates the need for media blasting or chemical stripping.

What You Need to Know:

• Material: Forged 7075-T6 Aluminum. This is the good stuff.
• Finish: Raw, unanodized, uncoated aluminum. It will have a dull, metallic gray appearance and is susceptible to surface oxidation (a light, non-structural film) if left untouched in humid conditions. Have your finishing plan ready.
• Compatibility: Forms the lower receiver for a standard AR-15 pattern rifle. Compatible with 5.56/.223, .300 BLK, 6.5 Grendel, and more.
• Engraving: “Fire” and “Safe” selector markings are pre-engraved.
• Magwell: Fully broached for positive magazine insertion and release.
• Origin: Forged, machined, and packaged in the United States.
• Important Note: This is an 80% lower receiver. It is not a firearm and requires machining to be completed. You are responsible for complying with all federal, state, and local laws regarding the purchase, completion, and possession of an 80% receiver. Completion requires tools, skill, and a proper jig.

If you want a lower that’s ready to go straight out of the box with a protective finish, grab one of our standard anodized models. But if your build plan involves a custom color, pattern, or specialty finish that you want to apply yourself, this raw 80% lower is the only correct starting point. It’s the foundation for a rifle that is genuinely, from the metal up, your own.

Build it your way. Start with raw material.
