AR-15 Lower Receivers

AR-15 lower receivers form the foundation of your build, housing the fire control group and defining compatibility across components. Our selection of AR-15 lowers is built for reliable fit, long-term durability, and clean assembly—whether you’re starting a first build, upgrading an existing rifle, or creating a custom Cerakote setup.

FFL Transfer & Shipping Information

AR-15 lower receivers are serialized components and must ship to a valid Federal Firearms License (FFL) holder. After checkout, we will contact the FFL selected during purchase to verify their license before shipment.

Verification may take several business days. We recommend notifying your chosen FFL in advance to avoid delays.

Important FFL Notice

If FFL information cannot be verified and we do not receive a response within 30 days of purchase, the order will be released and a store credit will be issued, less a 15% restocking fee.

Choosing the Right AR-15 Lower Receiver

When selecting an AR-15 lower receiver, focus on compatibility, machining quality, and intended use. Most builders choose forged mil-spec lowers for their balance of strength, affordability, and parts compatibility, while others prioritize cosmetic finishes or specific roll marks for custom builds.

A properly machined lower helps reduce receiver play, ensures smooth assembly, and supports long-term reliability across the platform.
