FN15 Patrol Lower Receiver Assembly | FN America

The FN15 Patrol Complete AR-15 lower receiver from FN America is a factory-assembled lower that includes the trigger, magazine release, and a Mil-Spec stock installed. The receiver is manufactured from 7075-T6 aluminum and finished in black anodize, and it is configured for use with .223 Rem/5.56 NATO components. This lower is intended for builders and shooters assembling a patrol-style or range-focused AR-15 configuration.

Appropriate applications include range practice and competition or match-style shooting where a factory-complete lower provides a consistent starting point for upper selection and final assembly. The factory-installed controls and stock make it suitable for straightforward integration into AR-15 builds without separate lower-component installation.
