The TacFire BU-9MM-10 Pistol Upper Assembly brings a streamlined AR-platform 9mm Luger upper together in a ready-to-install package. Built around a 10" black nitride barrel and a black anodized 7075-T6 aluminum receiver, it pairs a full-length top rail with a lightweight M-LOK handguard for modern accessory mounting and clean lines. This complete upper includes the bolt carrier group, simplifying your build and ensuring consistent fit and function.

Designed for shooters who want to convert or build a dedicated 9mm AR pistol, this upper is ideal for range use, training, and recreational shooting where low recoil and affordable ammunition shine. The optic-ready configuration lets you choose your preferred sighting system, while the compact barrel length keeps the platform maneuverable without sacrificing reliability. TacFire’s attention to machining, finish quality, and component selection results in an upper that feels refined, durable, and ready for regular use.
