The TacFire Pistol Upper Assembly is a value-driven, complete 5.56x45mm NATO solution designed for AR-platform pistol builds. It features a 10 4150 steel barrel with a black nitride finish for enhanced corrosion resistance and a standard A2 flash hider. The 7075-T6 aluminum receiver is black hardcoat anodized and paired with a modular M-LOK handguard for accessory attachment. This assembly is plug-and-play, coming fully built with a bolt carrier group (BCG) and a charging handle, making it ready to pin onto any standard AR-15 lower receiver. Note: This is a complete upper assembly including the BCG and charging handle.
