What Problem Does the Aero Precision FCG Solve?

• Unreliable Trigger Performance: Eliminates issues like inconsistent trigger pull weight, gritty feel, or unpredictable resets often found in low-quality or worn-out FCGs.

• Cost-Effective Solution: Offers a high-quality, long-lasting solution without the significant investment required for highly specialized competition triggers.
• Adherence to Mil-Spec Standards: For those who prioritize parts that meet established performance and durability benchmarks, this kit delivers precisely that.

Understanding the Core Components: What’s Inside the Kit?

The Aero Precision Fire Control Group Kit is comprehensive, containing all the essential elements for a fully functional trigger system. Each component is manufactured to exacting specifications to ensure seamless operation and long-term durability.

1. Hammer: This is the component responsible for striking the firing pin, initiating the primer ignition. The Mil-Spec hammer in this kit is designed for consistent force delivery and reliable performance, featuring a durable finish to resist wear and corrosion.
2. Trigger: The curved trigger included in this kit provides a familiar and comfortable interface for the shooter's finger. Its design is ergonomic and consistent with military specifications, offering a predictable pull from shot to shot.
3. Disconnector: Working in tandem with the trigger and hammer, the disconnector is crucial for safe semi-automatic fire. It ensures that the hammer is caught after each shot and held back until the trigger is released, preventing "hammer follow" and maintaining a single shot per trigger pull.
4. Hammer Spring: This spring provides the necessary tension for the hammer to strike the firing pin with sufficient force. A high-quality hammer spring, as found in this Aero Precision kit, is vital for reliable primer ignition across various ammunition types.
5. Trigger Spring: The trigger spring determines the weight and feel of the trigger pull. A properly tensioned trigger spring ensures a crisp break and a defined reset, contributing to improved shooting accuracy and control.
6. Disconnector Spring: This small but critical spring helps the disconnector function correctly, ensuring it reliably catches the hammer and allows for proper trigger reset.
7. Hammer Pin: These precision-machined pins secure the hammer within the lower receiver. They are designed for tight tolerances to prevent wobble and ensure proper alignment.
8. Trigger Pin: Similar to the hammer pin, the trigger pin secures the trigger and disconnector assembly in place. Both pins are critical for the FCG's stability and function.

Each of these components works in harmony to deliver the characteristic reliable and predictable performance expected from a Mil-Spec AR-15/AR-10 trigger. The inclusion of all necessary springs and pins means you have everything required for a complete installation.

The Advantages of Mil-Spec: Why It Matters

"Mil-Spec" is often used as a benchmark for quality and reliability in the firearms industry. For the Aero Precision Fire Control Group, it signifies adherence to specific military standards for materials, dimensions, and performance. But what does this mean for you, the user?

This translates to exceptional durability and long-term reliability for civilian applications. You can trust that the Aero Precision Mil-Spec FCG will perform consistently when it matters most.

This consistency is crucial for effective training and practical application, as it allows the shooter to anticipate the shot accurately.
• Ease of Maintenance and Replacement: Because Mil-Spec parts are standardized, finding replacement components or conducting maintenance is straightforward. The design is familiar to countless armorers and enthusiasts, simplifying any future work on your firearm.
• Cost-Effectiveness over Lifetime: While perhaps not the cheapest option upfront, the durability and longevity of Mil-Spec components mean fewer replacements and less downtime over the life of your rifle, making it a sound long-term investment.
