Faxon AR-15 Forged 7075-T6 Mil-Spec Stripped - Lower Receiver

The serialized foundation of a Faxon-built AR-15 — machined start to finish in-house. The Faxon AR-15 Forged Stripped Lower Receiver starts with a 7075-T6 aluminum forging and is CNC machined from forging to final inspection at Faxon's Cincinnati facility, with an integrated tensioning screw that lets you dial in the upper-to-lower fit exactly where you want it.

The Faxon AR-15 Forged Stripped Lower Receiver is a 7075-T6 aluminum forged and CNC-machined AR-15 lower receiver built to mil-spec standards for broad compatibility with standard AR-15 components, featuring an integrated tensioning screw for fine-tuned upper-to-lower interface control.

Four features define this lower as a precision-minded build foundation. CNC machining from forging to finish — performed entirely in-house at Faxon's Cincinnati facility — maintains dimensional control across the receiver rather than relying on tolerance accumulation through multiple machining stages, producing repeatable fit and function with mil-spec components. 7075-T6 forged aluminum provides the strength-to-weight ratio and grain structure that forged lowers offer over billet alternatives, with the structural integrity required for any caliber or configuration built on a standard AR-15 lower. The integrated tensioning screw allows the builder to fine-tune the interface between upper and lower receivers, reducing or eliminating receiver wobble without requiring shimming or aftermarket solutions. Faxon's QC process checks receivers against strict dimensional criteria before they ship, providing an additional layer of verification beyond standard production tolerances.

Compatible with mil-spec AR-15 upper receivers, lower parts kits, buffer systems, and furniture. Stripped configuration ships without internal components. FFL transfer required — serialized receiver.

7075-T6 forged aluminum, CNC machined in-house. Mil-spec geometry. Integrated tensioning screw. Made in the USA.

Ideal for custom AR-15 builds, precision-minded builders who want a tighter upper-to-lower fit, and quality upgrades from worn or damaged receivers.
