Fortis License Gen Lower receiver Rifle

The Fortis License Gen II AR-15 lower receiver is a precision-engineered component designed for operators, gunsmiths, and shooters who demand accuracy and reliability in custom rifle builds. As the regulated firearm component that houses the trigger group and fire control system, a quality lower receiver is the foundation of any AR-platform rifle. The Fortis Manufacturing lower receiver serves law enforcement, military personnel, and civilian marksmen who require tight tolerances and consistent performance across thousands of rounds. This component is essential for anyone building or upgrading an AR-15 platform rifle for duty, competition, or training applications.

Fortis Manufacturing has engineered this Gen II lower receiver with precision CNC machining to exacting military specifications, ensuring proper feed geometry, flawless trigger group installation, and dimensional consistency that eliminates reliability issues common in lower-quality forgings. The receiver features a reinforced fire control cavity and optimized pocket dimensions that accommodate both mil-spec and enhanced trigger assemblies without binding or excessive wear. At just 1 pound, the forged aluminum construction balances structural integrity with weight efficiency—critical for operators who carry their rifles extensively. The Gen II design incorporates lessons learned from field deployment, refining the magazine well geometry and hammer pin lugs to withstand sustained automatic fire environments and high-round-count training cycles.

This lower receiver is ideal for gunsmiths, armorsmiths, and end-users building duty rifles, precision 6.5 Creedmoor or .308 Win uppers, or modular carbines that demand platform interchangeability. Installation requires basic AR-15 assembly knowledge: the receiver accepts standard mil-spec fire control groups, buffer tubes, and stocks without modification. As a federal firearm component, the lower receiver is subject to FFL transfer requirements and must be received and registered through a licensed firearms dealer. Whether you're assembling a law enforcement duty weapon, a patrol carbine, or a precision competition build, the Fortis License Gen II lower receiver provides the foundation for a reliable, accurate platform that performs under demanding conditions.
