80 Percent Lower | 80% Lowers | Very Fast Shipping

If you have been shopping for an 80 percent lower, you already know the challenge: finding a raw blank that is precisely machined, ready for your build, and shipped before you lose momentum. That is exactly what we deliver here. Whether you are starting a fresh pistol build or stacking extras for future projects, our 80% lowers offer the cleanest pocketing, the tightest jig fit, and the fastest turnaround in the industry. No waiting weeks. No vague tracking numbers. Just a solid foundation that puts the control back in your hands.

Overview

An 80 percent lower is exactly what it sounds like: a receiver that is 80% finished from the factory, leaving you the final machining steps to complete the fire control group pocket and trigger pin holes. This means you can build a functional firearm from a raw block of aluminum or polymer without a serial number, without an FFL transfer, and without the paper trail that comes with a completed receiver. Our 80% lowers are made from billet 7075-T6 aluminum, heat treated, and anodized for long-term durability. Each pocket is CNC machined to within 0.001 inch of spec, so your jig locks in solid and your drill bit tracks true. We stock these in deep quantities, which is why we can offer very fast shipping on every order.

Features & Specs

• Manufacturer: 80 Arms. Category: Parts. Material: 7075-T6 billet aluminum, Type III Class 2 hardcoat anodized.
• Precision CNC machined pocket with .003 inch tolerance. Compatible with all standard AR-15 jigs and drill press setups.
• Includes 4-40 threaded rear takedown pin detent hole. No additional drilling required for that step.

These 80% lowers are designed for the home builder who values consistency. The trigger pocket walls are square and smooth, the fire control group shelf is flat, and the bolt catch channel is fully cut. You will not have to chase burrs or file down high spots. Simply clamp your jig, drill the three holes, and finish the pocket with a router or end mill. Every lower is individually inspected before packaging. We also include a small bottle of cutting oil and a deburring tool with each purchase.

Who It’s For

This 80 percent lower is for the builder who wants to learn the platform from the ground up. It is for the shooter who wants a truly custom firearm without the serial number. It is for the prepper who wants to stack components now, knowing they can complete the build later when time allows. If you have a drill press, a vise, and a basic router jig, you can finish this lower in about 90 minutes. We recommend it for intermediate to experienced builders, but a motivated beginner with good instructions and patience can absolutely succeed. The blank is forgiving, but the final result depends on your setup and attention to detail.

Shipping & FFL

We ship these 80% lowers directly to your doorstep with no FFL transfer required. Because they are not yet a firearm under federal law, they ship via USPS Priority Mail or UPS Ground, whichever is faster to your ZIP code. Orders placed before 2 PM Eastern time typically go out the same business day. That is what we mean by very fast shipping. We do require that you are at least 18 years old to purchase, and that you comply with all local, state, and federal laws regarding the ownership and completion of unserialized receivers. Some states and localities have specific restrictions on 80 percent lowers. It is your responsibility to check your local laws before ordering. By purchasing, you confirm that you are legally allowed to own and complete this product.
