Yankee Hill Machine AR-15 Stripped Billet Lower Receiver – Precision CNC Machined, Mil-Spec Compatible

YHM originally designed a Billet lower that mimicked a standard (forged) lower receiver, but after seeing the prototype production they decided to go with a receiver that was more stylized, something that didn’t look like every other AR-15 on the planet. It was this mindset that helped YHM arrive at the Model-57, and in turn this lower receiver. This lower is crafted from 7075-T6 aluminum and has a hardcoat anodized matte black finish. It features over-sized magazine well chambers for easier magazine changes. It accepts all generations of PMAG’s and Mil-Spec Upper receivers. It has a built in oversized machined trigger guard . It fits all standard parts (except for a trigger guard) and still fits, and functions with your standard upper receivers.

Key Features:

• CNC-machined billet aluminum construction – stronger than forged alternatives

• Mil-spec component compatibility – works with standard AR-15 parts and uppers

• Flared magazine well for faster, smoother reloads

• Enhanced geometry and clean lines for a sleek, modern aesthetic

• Durable Type III hardcoat anodized finish in matte black

• Precision-toleranced for improved build quality and performance

• Made in the USA by Yankee Hill Machine

Perfect For:
Builders seeking a high-performance AR-15 billet lower for tactical, competition, or custom rifle builds. The YHM billet receiver delivers strength, function, and style in one elite foundation.
