TacFire Rifle Upper Assembly Features The TacFire Rifle Upper Assembly arrives fully built chambered in 9mm Luger and ready to drop onto a compatible AR-platform lower receiver. The 16 inch barrel carries a black nitride finish that resists corrosion and wear through repeated range sessions while an A2 flash hider at the muzzle helps control muzzle flash during rapid fire. The included bolt carrier group and charging handle are matched to the 9mm blowback operating system eliminating the guesswork of sourcing a compatible BCG separately. This turnkey approach lets a builder go from parts to a functioning rifle configuration with minimal additional assembly. The upper receiver itself is machined from aluminum and finished in a durable black anodized coating that stands up to regular handling and holster wear. An M-LOK handguard wraps the barrel giving the shooter free float mounting space for lights foregrips slings and other accessories along the full length of the rail. The upper ships with no sights installed leaving the shooter free to add optics or iron sights suited to their own setup. Builders adding a 9mm upper to their AR-15 lower for range use training or a lightweight carbine build will find this a straightforward complete solution.
