AR-15 9mm Dedicated Stripped Billet Upper Receiver (Anodized Royal Purple)

Description

This AR-15 9mm Dedicated Stripped Billet Upper Receiver provides the foundational component for building a custom 9mm platform. Crafted from T6 6061 Billet aluminum, it offers a robust and precise base for assembly. The receiver features a 1913 Picatinny Rail flat top, ensuring compatibility with a wide range of optics and accessories without requiring additional mounting hardware. The exterior is finished in Anodized Royal Purple, providing both corrosion resistance and a distinct visual identity that sets it apart from standard black or grey finishes.

The design incorporates a smooth “Slab Side” profile, which reduces weight and snag points while maintaining structural integrity. Key dimensional details include an ejection port opening measuring 0.61″ Width X 2.30″ Length, engineered to align correctly with standard 9mm bolt carriers and charging handles. The unit weighs 10.2 oz, contributing to a balanced upper assembly when paired with appropriate lower components. As a stripped receiver, it is supplied without internal parts, allowing builders to select specific firing mechanisms, gas systems, and buffer weights tailored to their build requirements.

Compatibility is a primary consideration for this upper. It is designed to match up with any brand 9mm lower receiver, including popular options such as New Frontier, Palmetto State Armory, and others. This ensures flexibility in choosing the lower components that best suit your ergonomic and functional preferences. The receiver is manufactured in the USA, adhering to domestic production standards for quality control and material integrity. This piece serves as the critical link between your chosen lower receiver and the barrel, gas system, and handguard, forming the core of a reliable AR-9 platform.
