Sharps Gen2 Overthrow Billet Lwr Brz

The Sharps Gen2 Overthrow Billet Lower Receiver in Bronze is a precision-machined 7075-T6 aluminum lower receiver built by Sharps Bros., a manufacturer known for custom AR-15 components and complete firearm designs. This billet lower delivers the structural integrity and tight tolerances demanded by serious AR-platform builders and operators who require drop-in compatibility with standard mil-spec internal parts and upper receivers.

Constructed from 7075-T6 aluminum—an aerospace-grade alloy selected for its strength-to-weight ratio—the Gen2 Overthrow maintains full compatibility with all mil-spec trigger groups, fire control components, and aftermarket upper receivers. The billet manufacturing process allows tighter dimensional control than forging, reducing tolerance stack and improving fit and function over repeated cycles. The bronze anodized finish provides both aesthetic appeal and corrosion resistance, critical for rifle systems exposed to variable environmental conditions.

This receiver serves precision rifle builders, law enforcement armory upgrades, and civilian shooters constructing mil-spec AR-15 platforms for duty, competition, or training applications. At 0.94 lbs, the lower receiver contributes minimal weight to the completed rifle while maintaining the durability required for sustained rapid fire, magazine changes, and environmental exposure. Sharps Bros. has transitioned from a custom shop to a full manufacturing organization, bringing manufacturing discipline and design consistency to every component.

The AR-15 lower receiver remains the federally regulated component of the rifle platform; builders should verify compliance with all applicable federal, state, and local firearms regulations before assembly and ownership. This billet lower is ready to accept standard controls, trigger groups, and upper receivers without modification.
