AR15 Raw Lower Receiver [80%] Overview

The AR15 Lower Receiver [80%] is an unfinished receiver blank that provides the foundation for your DIY rifle or pistol build. Machined from raw aluminum to mil-spec standards, this 80% lower has been precision-machined to the point where it’s not yet a firearm under federal law. The fire control pocket remains unmilled and the pin holes undrilled, leaving the final steps for you to complete at home.

Once finished, this AR15 Lower Receiver [80%] is identical in form and function to any stripped lower you’d buy from a gun store. It accepts standard mil-spec lower parts kits, buffer assemblies, triggers, grips, and any appropriately chambered upper receiver. Build a 5.56/.223 rifle, a .300 Blackout pistol, a 6.5 Grendel hunter: the platform is yours to configure.

Raw aluminum finish ships ready for you to apply your own coating after machining, or leave it natural. No FFL required. Ships direct to your door in most states.

What Makes the AR15 Raw Lower Receiver [80%] Different

Mil-Spec Dimensions
This AR15 Lower Receiver [80%] is machined to military specification tolerances. That means guaranteed compatibility with standard AR-15 parts: any mil-spec lower parts kit, any buffer tube assembly, any upper receiver. No fitting, no filing, no surprises. Once you complete the machining, your lower functions exactly like a factory receiver.

Quality Aluminum Construction
Constructed from high-quality aluminum, this 80% lower offers the ideal balance of lightweight portability and exceptional durability. The forging process compresses the aluminum grain structure, resulting in superior strength compared to cast alternatives. This is a receiver built to last.

Raw Finish for Custom Coating
The AR15 Lower Receiver [80%] ships in raw aluminum finish, tumbled and deburred for a clean starting point. After you complete the machining, apply Cerakote, Duracoat, anodizing, or any coating you prefer. Match your upper, create a custom color scheme, or leave it raw: the choice is yours.

Not a Firearm
Under federal law, an 80% lower is not classified as a firearm because the fire control pocket has not been milled and the selector/trigger pin holes have not been drilled. That means no FFL transfer, no serial number requirement (federally), and no paperwork. You complete the final machining steps at home using an 80% jig and standard tooling.

AR15 Raw Lower Receiver [80%] FAQ

What is an AR15 Lower Receiver [80%]?
An 80% lower is an unfinished receiver blank. The exterior is fully machined, but the fire control pocket (where the trigger, hammer, and safety go) has not been milled, and the pin holes have not been drilled. Because it cannot accept a fire control group in this state, the ATF does not classify it as a firearm. You complete the final machining at home to create a functional stripped lower receiver.
What tools do I need to finish the AR15 Lower Receiver [80%]?
You’ll need an 80% lower jig (sold separately), a router or drill press, and appropriate end mills and drill bits. Some jigs are designed for handheld routers, others for drill presses or milling machines. Follow the jig manufacturer’s instructions for specific tooling requirements.
What can I build with this AR15 Lower Receiver [80%]?
Once completed, this lower accepts any standard AR-15 upper receiver. You can build rifles or pistols chambered in 5.56 NATO, .223 Remington, .223 Wylde, .300 Blackout, 6.5 Grendel, .458 SOCOM, and other AR-15 compatible calibers. The lower itself is caliber-agnostic: the upper determines what you’re shooting.
Is the AR15 Lower Receiver [80%] legal?
Under federal law, 80% lowers are not classified as firearms and can be purchased without an FFL. However, state and local laws vary significantly. Some states have banned 80% lowers entirely. Others require serialization of all home-built firearms. It is your responsibility to verify the laws in your state before ordering. We do not ship to restricted states.
Do I need to serialize my finished AR15 lower?
Federal law does not require serialization of firearms manufactured for personal use. However, several states (including California) require home-built firearms to be serialized. Always verify your state and local laws. If you intend to sell or transfer the firearm, additional federal requirements apply.
What parts do I need to complete my build after finishing the lower?
After machining, you’ll need: a lower parts kit (LPK) including trigger, hammer, safety, grip, and springs; a buffer tube assembly (buffer, spring, tube, and stock or brace); and an upper receiver assembly (upper, barrel, handguard, BCG, and charging handle). Complete upper assemblies are available that bolt directly onto your finished lower.
Why is this receiver sold in raw aluminum finish?
Raw aluminum finish allows you to apply your own coating after machining. Anodizing or Cerakoting a completed lower gives you a uniform finish without exposed machining marks. If you prefer a pre-finished receiver, anodized options may be available separately.
