The TacFire Complete Upper with BCG (TacFire part no. BU30016) is a .300 AAC Blackout upper assembly with a 16-inch barrel, sold complete with a bolt carrier group so it’s ready to drop onto a compatible lower receiver. The barrel wears a Black Nitride finish for corrosion resistance and smooth cycling, and the upper ships optic-ready with no iron sights included. It’s a straightforward way to add a 300 Blackout upper to an existing AR-15 lower without sourcing a barrel, BCG, and finish separately. Finished in black to match standard AR-platform furniture, it’s built as a complete, ready-to-run package.
