Precision machined from 7075-T6 aluminum to mil-spec dimensions, this lower is finished in a Type III hardcoat anodizing for long-term durability against wear and corrosion. The .250-inch takedown holes and Safe/Fire indicators match standard AR-15 conventions, so any mil-spec lower parts kit and components drop right in without modification. This black lower ships stripped, giving builders full control over the fire control group, stock, and grip they pair with it to complete a rifle built exactly to their specifications.

Geissele Automatics was established in 2004 with a mission to build the highest quality, most reliable triggers for competition shooters. Their Hi-Speed National Match trigger was so well received that the Department of Defense asked them to produce a select-fire version for U.S. Special Operations, and Geissele has since become a trusted name in components for the warfighter and competitor alike.
