TacFire AR Barrel — 9mm NATO, 16" — Black Nitride, 4150 Chrome Moly Vanadium Steel, Threaded, 1:10" Twist (Model BAR9MM16BN / UPC 745557100611)
Upgrade your AR-15/AR-9 build with a purpose-built 9mm barrel engineered for durability, consistency, and range performance. The TacFire BAR9MM16BN is a 16-inch, 9mm NATO-caliber barrel machined from 4150 chrome-moly vanadium steel, finished in hard black nitride for superior corrosion and wear resistance, and cut with a 1:10" twist rate to stabilize the most common 9mm projectile weights. Finished with a threaded muzzle and optimized dimensions for AR-15 platform integration, this barrel delivers reliable feeding, predictable accuracy, and long service life for shooters building compact carbines, PCCs, or full-length AR-9 rifles.
Why the TacFire BAR9MM16BN matters
Whether you’re building a practical PCC for competition, a defensive AR-9 carbine, or a versatile range gun, the barrel is the heart of the rifle. The BAR9MM16BN gives you:
Material integrity: 4150 CMV steel provides proven strength and hardness for long-term use.
Durable finish: Black nitride (salt bath nitrocarburizing) increases surface hardness, reduces friction, and resists corrosion for easier maintenance and longer bore life.
Balanced ballistics: A 16" length gives a useful compromise between maneuverability and muzzle velocity, improving ballistic performance versus very short barrels while keeping the platform compact.
Versatile twist: The 1:10" twist rate stabilizes the most popular 9mm bullets — from 90–147 grains — for consistent accuracy across defensive, target, and match loads.
Threaded muzzle: Ready for your choice of compensator, muzzle device, or adapter (thread pitch varies by spec — verify exact thread pitch for your intended muzzle accessory).
Key Features & Benefits
Model: TacFire BAR9MM16BN
UPC: 745557100611
Caliber: 9mm NATO / 9×19mm Luger
Barrel Length: 16.00 inches — ideal for AR-9 carbines and full-length AR-15 conversions tuned to 9mm.
Twist Rate: 1:10" — optimized for most 9mm projectile weights used in competition and defensive loads.
Material: 4150 Chrome Moly Vanadium steel (heat-treated, stress relieved) for consistent strength and longevity.
Finish: Black Nitride — low friction, corrosion resistant, easier cleaning, and improved wear characteristics.
Muzzle: Threaded — accepts muzzle devices or adapters (verify thread spec for accessories).
Intended Platform: AR-15 / AR-9 style uppers and pistol/carbine builds configured for 9mm bolt carriers and magazine systems.
Use Cases: Competition PCC, range training, defensive carbine, suppressed or unsuppressed 9mm setups.
Performance Expectations & Ballistics
A 16" 9mm barrel offers measurable velocity improvements over short pistol-length barrels, which can translate into better terminal performance and slightly flatter trajectory for many loads. Expect:
Improved follow-through and sight radius for more consistent groups.
Compatibility with common 9mm bullet weights; the 1:10" twist stabilizes bullets from ~90 gr to heavier 147 gr loads.
Reliable cycling when paired with the correct 9mm bolt, magazine system, and appropriate gas/roller/dummy setup in AR-9 platforms.
Actual velocity and point-of-impact will vary by ammunition brand, load, and the specific firearm configuration — always chronograph and pattern test to dial in loads for your setup.
Fitment & Compatibility (Things to verify)
AR-9 vs AR-15 lowers: Ensure your lower, bolt carrier group, and magazines are configured for 9mm operation (9mm BCG or dedicated 9mm bolt, appropriate magazine well and mags).
Barrel extension & headspace: Proper barrel extension and headspace are critical. Have installation and headspace verified by a qualified armorer if you’re not experienced.
Muzzle device threads: This barrel is supplied threaded for muzzle devices — verify the exact thread pitch in the product spec or with the seller before purchasing muzzle devices or suppressor adapters.
Gas system (if applicable): Many 9mm AR builds use blowback/diode/dedicated gas blocks; ensure your upper/BCG arrangement matches the barrel’s intended system.
Installation & Armorer Notes (High-Level)
Use standard armorer tools and follow torque specifications for your barrel nut and handguard system.
Confirm headspace and proper fit of the barrel extension to the bolt/BCG. Improper installation can cause malfunctions or unsafe conditions.
If you plan to run a suppressor, use the correct adapter/mount matching the barrel’s thread pitch and ensure gas flow and backpressure are compatible with your BCG/system.
If you are unsure about headspace, torque values, or compatibility, have the barrel installed by a qualified gunsmith.
Care & Maintenance
Cleaning: Nitride finish is corrosion resistant but still benefits from routine cleaning. Use quality bore solvent and brushes rated for pistol bore sizes; remove carbon/copper fouling after each range session.
Inspection: Periodically check the muzzle threads, crown, and bore for signs of wear or erosion, especially if used suppressed or with high round counts.
Protection: Wipe exposed metal with a light film of protective oil for long-term storage.
Frequently Asked Questions (FAQ)
Q: Is this barrel compatible with all AR-15 uppers?
A: It fits AR uppers designed for 9mm conversion or AR-9 uppers. Confirm your upper/bolt/BCG and magazine system are 9mm-capable before installing.
Q: What muzzle devices will fit?
A: The barrel is threaded for a standard muzzle device; check the manufacturer listing or product spec to confirm the exact thread pitch before purchasing a compensator, flash hider, or suppressor adapter.
Q: Why choose 4150 CMV steel with nitride finish?
A: 4150 CMV is a widely used, heat-treated barrel steel with excellent strength and longevity. Black nitride greatly improves surface hardness, corrosion resistance, and reduces friction compared to bare steel or parkerized finishes.
Who Should Buy the TacFire BAR9MM16BN?
PCC competitors building full-length 9mm carbines that want higher muzzle velocities and improved accuracy.
Tactical and defensive users who prefer a 9mm carbine for lower recoil and affordable training ammo.
Range rigs & trainers who need a durable, low-maintenance 9mm barrel for high round counts.
Suppressor users who want a nitride-finished barrel that tolerates the increased wear and fouling associated with suppressed shooting (verify thread pitch and adapter compatibility).
