Aero Precision FCG Kit (C)

The Aero Precision Fire Control Group Kit (C) is a mil-spec standard fire control group designed to streamline AR-15 and AR-308 platform builds. This complete FCG kit provides all critical internal components needed to establish a functioning trigger assembly, enabling shooters to move past frame preparation and move directly to range testing and function validation.

The kit includes seven essential components: hammer, trigger, disconnector, trigger/hammer pin, trigger spring, hammer spring, and disconnector spring. Each component meets mil-spec tolerances, ensuring proper hammer fall, trigger reset, and disconnector function across the entire operating envelope. The mil-spec standard classification means these parts are manufactured to military specification MIL-SPEC parameters, a critical baseline for reliability-critical systems where function cannot be compromised.

This fire control group kit serves builders and gunsmiths who source components individually or require a validated assembly package for AR platform rifles. Whether outfitting a duty rifle, precision build, or training carbine, the FCG is the foundation of reliable trigger function and requires proper installation per manufacturer specifications and applicable regulations in your jurisdiction.

Aero Precision fire control groups are recognized within the precision rifle and tactical communities for consistent performance across manufacturing batches. The Aero Precision FCG Kit (C) represents a complete, verified assembly suitable for AR-15 and AR-308 platforms, eliminating the complexity of sourcing individual springs and pins separately while maintaining mil-spec reliability standards.
