The TacFire BU-556-10 Pistol Upper Assembly brings a compact 5.56x45mm NATO setup to your AR-platform, pairing a 10" black nitride barrel with a black anodized 7075-T6 aluminum receiver and M-LOK handguard. This complete upper includes a bolt carrier group and features an A2 flash hider at the muzzle, giving shooters a ready-to-mount solution that balances durability, reliability, and modern styling.
Designed for AR-15 pistol builds and short, handy configurations, this upper is well suited for range use, training, and general-purpose shooting where a lighter, more maneuverable setup is preferred.
