Faxon Ion Ultralight Complete - Upper Receiver 5.56 16"

The Faxon Ion Ultralight Complete Upper Receiver 5.56 16" is purpose-built for shooters demanding maximum performance with minimal weight penalty. Designed for AR-15 platforms, this complete upper serves law enforcement tactical units, military-adjacent civilian operators, and precision shooters who refuse to compromise between firepower and mobility.

Whether configured for duty use, competition, or field operations, the Ion Ultralight addresses a critical need: delivering battle-proven reliability without the bulk of conventional uppers. Faxon's Ion platform leverages advanced materials and refined geometry to achieve a lightweight design while maintaining durability through rigorous testing protocols.

This upper arrives fully assembled and headspaced, eliminating installation complexity and ensuring immediate deployment capability. The complete configuration includes a bolt carrier group, charging handle, and properly staked gas key—everything needed to marry to a lower receiver. Law enforcement patrol units and reserve military personnel benefit most from this weight-conscious design, particularly in extended operations.
