AR-15 9MM Complete Upper Receiver with 4 inch M-LOK and Socom Mini

Description

This AR-15 9MM Complete Upper Receiver is a fully assembled unit manufactured in Scottsdale, Arizona, designed for builders seeking a functional 9mm Luger platform. The assembly features a 5.5-inch barrel crafted from 4150 Chrome Moly Vanadium steel with a 1:10 twist rate, providing the necessary stability for standard 9mm ammunition. The barrel is finished with a QPQ Nitride treatment, which ensures corrosion resistance and facilitates easy cleaning after use. This specific configuration includes a 3-inch Micro Socom Fake Suppressor at the muzzle, which serves as a functional muzzle device and aesthetic component for the build.

The upper receiver itself is constructed from 8620 Steel, offering a robust foundation for the internal components. It is finished with Type III Hard Coat Anodizing in Black, providing a durable, non-reflective surface that withstands harsh operating conditions. The unit is equipped with a 4-inch Free Float M-LOK Handguard, which allows for the attachment of accessories while keeping the handguard clear of the barrel to prevent heat transfer. The handguard attachment system utilizes the M-LOK standard, ensuring compatibility with a wide range of modern accessories.

Inside the receiver, the included Bolt Carrier Group is machined from 9310 Steel, a high-grade material known for its strength and fatigue resistance. The bolt carrier is ramped to fit standard AR-15 hammers, ensuring reliable cycling with existing lower receiver components. This complete upper receiver is engineered to work with both Colt-style and Glock-style magazines, providing versatility in magazine selection for the user. The entire assembly is delivered as a Stripped Upper, ready for integration into a custom AR-15 pistol or PCC build. The combination of premium materials, precise machining, and thoughtful design makes this upper receiver a reliable choice for experienced builders looking to complete their 9mm AR-15 project.
