Aero Precision FCG Kit (C)

The Aero Precision Fire Control Group Kit (C) is a mil-spec standard fire control group designed for AR-15 and AR-308 platform builds. This complete FCG kit includes all critical internal components necessary for a functioning trigger assembly, allowing shooters to bypass frame preparation and proceed directly to range testing.

The kit comprises seven essential components: hammer, trigger, disconnector, trigger/hammer pin, trigger spring, hammer spring, and disconnector spring. Each component adheres to mil-spec tolerances, ensuring reliable hammer fall, trigger reset, and disconnector function across the operating envelope. This adherence to military specifications is crucial for reliability in systems where function cannot be compromised.

Ideal for builders and gunsmiths, the Aero Precision FCG Kit (C) is perfect for those who source components individually or need a validated assembly package for AR platform rifles. Whether outfitting a duty rifle, precision build, or training carbine, this fire control group kit is foundational for reliable trigger function and requires proper installation according to manufacturer specifications.
