Sig Sauer MCX upper.

1. Sig Sauer MCX Upper Receiver:

   • The upper receiver from the MCX provides the core of the firearm. The MCX is known for its unique operating system, featuring an internal recoil and short-stroke piston system, eliminating the need for a traditional buffer tube.

2. AR 2 Stage Matchlite DUO Trigger:

   • This trigger assembly is designed with a 2-stage mechanism, providing a more refined and controlled trigger pull. A quality trigger can enhance accuracy and control during firing.

3. 90 Degree Muzzle Adapter:

   • The 90-degree muzzle adapter suggests a different orientation for attaching muzzle devices. This could be useful for specific configurations or preferences in terms of accessories like muzzle brakes or suppressors.

4. X-Fold Stock Adapter:

   • The X-Fold stock adapter allows for the installation of an X-Fold folding stock. Folding stocks are valuable for compactness and ease of transport, especially in situations where space is a concern.

5. MCX to M400 Lower Receiver Adapter:

   • This adapter likely facilitates the compatibility between the MCX upper receiver and the lower receiver of an AR-15, specifically the M400 variant. This component is crucial for ensuring a proper fit and function between the different platforms.

6. 11.5” Barrel:

   • The 11.5-inch barrel is included in the kit, determining the overall length of the firearm. This length is often chosen for a balance between maneuverability and ballistic performance, making it suitable for various applications.

By combining these components, users can create a firearm with the unique features of the MCX operating system, the folding stock capability, and the compatibility with AR-15 lower receivers.
