TacFire BU-9MM-16 Rifle Upper Assembly — 9mm Luger, 16" Black Nitride Barrel, 7075-T6 Upper, Free-Float M-LOK® Handguard, Includes BCG (BU9MM16 • UPC 729205504358)
Build a smooth-shooting, soft-recoiling AR-pattern carbine with the TacFire BU-9MM-16 complete upper. Chambered in 9mm Luger, this upper blends a durable 16" black nitride barrel with a strong, black-anodized 7075-T6 aluminum receiver and a slim, free-float M-LOK handguard. Even better, it includes a bolt carrier group (BCG), so you can pin it to your lower and get to the range faster. Whether you’re setting up for PCC training, home-range practice, or an affordable carbine build, the BU-9MM-16 focuses on reliability, clean ergonomics, and easy maintenance.
Why Choose a 16" 9mm AR Upper
Low recoil & fast follow-ups: Blowback 9mm carbines are easy to control and inexpensive to train with.
Velocity boost: A 16" barrel wrings more speed from 9mm loads than pistol lengths, improving consistency and expanding ammo options.
Range & PCC friendly: Works great for steel, transitions, and drills, with less blast than short barrels.

Caliber: 9mm Luger (9×19)
Barrel: 16" black nitride (corrosion-resistant, smooth to clean), threaded muzzle (verify pitch before installing a device)
Upper Receiver: 7075-T6 aluminum, black anodized for strength-to-weight and durability
Handguard: Slim free-float M-LOK® handguard for accessories without adding bulk
Bolt Carrier Group: Included — a proper 9mm BCG for plug-and-play assembly
Platform: AR-pattern 9mm (pistol-caliber carbine)
Model / UPC: BU9MM16 / 729205504358
Built for Real-World Reliability
Nitride barrel life: The nitride treatment hardens the surface, improves wear resistance, and keeps carbon fouling from sticking.
Free-float accuracy: By isolating the barrel from handguard pressure, the upper helps maintain consistent point of impact across positions.
Accessory-ready: M-LOK slots at practical positions support lights, hand stops, QD sling sockets, and more—without extra weight.
Balanced handling: A slender handguard and mid-length real estate give you optimal support-hand placement for controlling recoil.
Ideal Use Cases
PCC competition & training: Soft recoil for faster splits and transitions.
Budget-smart practice: 9mm ammo costs make high-volume range days more accessible.
Ranch/utility carbine: Simple operation and accessory flexibility for everyday tasks.
Safety Note: 9mm uppers must be used with 9mm-specific lowers or magwell adapters and 9mm magazines. Never attempt to fire 9mm in a 5.56/.223 upper or vice versa.
Compatibility & Setup Tips
Lower Receiver: Use an AR-15 9mm dedicated lower (e.g., Glock-pattern or Colt-pattern) or a quality magwell adapter matched to your magazines.
Buffer System: Blowback 9mm often runs best with heavier buffers and robust springs; tune for your ammo and whether you add a suppressor.
Magazines: Run clearly marked 9mm mags to avoid cross-loading. Quality mags improve last-round bolt-hold-open (LRBHO) performance when your lower supports it.
Muzzle Devices: Confirm the thread pitch (commonly 1/2×28 or 1/2×36 in 9mm) before installing brakes or suppressors.
Zero & Dope: 9mm ballistics drop faster than rifle rounds; confirm zero at your match or training distance (e.g., 25/50 yards).
What You’ll Notice on Day One
Clean ergonomics: The slim free-float M-LOK handguard and 16" barrel create a steady, controllable front end.
Less fouling stress: Nitride surfaces wipe down quickly after high-round-count sessions.
Ready to run: With the included BCG, assembly is straightforward—pin to your lower, lube, and verify function.

Installation (Best Practices)
Clear & Safe: Verify your lower is unloaded; remove any magazine and visually/physically inspect.
Join Receivers: Align the upper and insert takedown/pivot pins.
Lubrication: Lightly lube the 9mm BCG rails and contact points.
Function Check: Hand-cycle, verify bolt catch operation (if your lower supports LRBHO), and ensure magazines seat/lock.
Live-Fire Tune: Test with your chosen ammo; adjust buffer/spring weight if needed for optimal ejection and bolt hold-open.
Care & Maintenance
Routine wipe-down: Blowback 9mm runs dirty—clean the bolt face, extractor, and chamber regularly.
Inspect wear points: Keep an eye on ejector, bolt catch, and magwell adapter (if used).
Protect threads: Use a protector when no device is installed and apply anti-seize if recommended by your device maker.
