80 Percent Lower

80 Lower

An 80 lower, abbreviated from “80% lower receiver,” is an embryonic firearm chassis—molded from aluminum or polymer—that exists in a liminal, pre-functional state. It has not yet undergone the intricate metalwork or precision milling required to transform it into an operative component of a firearm.

In this unfinished guise, it eludes classification as a weapon by the ATF, allowing it to traverse the marketplace in numerous U.S. jurisdictions absent of serial inscriptions or bureaucratic filtration, such as background checks. This legal loophole permits private acquisition without federal oversight, presenting a discreet conduit for hobbyists and builders seeking autonomy in firearm fabrication.

80 percent lower

An 80 percent lower is a firearm component that’s almost a finished lower receiver. It lacks the final milling, meaning it’s not considered a firearm by law. That allows buyers to purchase it without serial numbers or background checks.

Building a firearm using an 80 lower is a rewarding project that combines craftsmanship, independence, and legal ownership. Whether you’re doing it for the challenge, the privacy, or the savings, this process demands knowledge, patience, and responsibility. As laws shift, staying informed is crucial—but for those ready to dive in, the 80 lower offers a powerful way to personalize your right to bear arms.

Foremost Advantages of an 80 Percent Lower Receiver

1. Bypasses Background Screening
   Due to its unclassified nature under federal regulation, this component slips beneath the radar of mandatory background scrutiny—streamlining your acquisition and preserving personal discretion throughout your build journey.

2. Freedom from Serial Inscription
   Unless dictated by specific state statutes, there’s no compulsion to imprint a serial identifier. This lends a cloak of privacy and confidentiality to your project, unmarred by registration.

3. Architect Your Ideal Firearm
   Whether envisioning an AR-15 platform or a Glock-inspired sidearm, the blueprint is yours to command. Tailor the aesthetics, hardware, and configuration down to the final pin and pigment.

4. Refine Mechanical Proficiency
   Engaging with the process of carving and assembling cultivates hands-on expertise. For many craftsmen and enthusiasts, this path proves both intellectually enriching and practically fulfilling.
