Hit the sweet spot between maneuverability and downrange performance. The TacFire 18" .308 Win Black Nitride Barrel is purpose-built for AR-10 / DPMS-pattern rifles, giving you the extra velocity of an 18-inch tube with the handling advantages of a midlength build. The black nitride treatment hardens the bore and exterior for superior wear resistance, corrosion protection, and easier cleanup—ideal for hunters, practical precision shooters, and anyone building a durable, all-weather .308 AR.
Why Choose the TacFire 18" .308 Barrel?
Balanced 18" Length: Adds velocity and dwell time versus 16" while staying handier than 20"—a proven pick for field rifles, DMR builds, and range work.
Black Nitride Inside & Out: Ferritic nitrocarburizing increases surface hardness, reduces fouling adhesion, and improves corrosion resistance for long service life.
AR-10/DPMS Compatibility: Designed around common large-frame AR specs for straightforward fit with quality receivers, handguards, and SR-25 pattern mags.
Accuracy-Focused Profile: Rigid 18" configuration supports consistent harmonics and repeatable groups with match or hunting ammunition.
High-Value Upgrade: Get durability and performance without boutique pricing—perfect for first builds and seasoned projects alike.

Performance You’ll Notice
Extended-Range Precision: Extra barrel length boosts velocity for 155–178gr bullets, tightening wind drift and vertical spread.
Reliable Cycling: Pair with the correct gas length and a .308-specific buffer system to achieve clean ejection and positive lock-back.
Simplified Maintenance: Nitride surfaces shrug off carbon—spend less time scrubbing and more time shooting.
Practical Weight & Balance: Manageable front-end weight keeps tracking smooth from barricades, tripods, and field positions.
Ideal Use Cases
Big-Game & Predator Hunting: Strong .308 ballistics with a manageable overall length for blinds and timber.
DMR / Practical Precision: Confidently ring steel from 300–800+ yards with good dope and glass.
All-Weather Ranch Rifle: Nitride protection and proven .30-cal performance for year-round property work.
Compatibility & Build Notes
Receiver Pattern: Match with DPMS/LR-308-pattern uppers and free-float handguards; use SR-25 pattern magazines.
Gas/Buffer Tuning: Combine the correct gas length with a .308 buffer, spring, and tube; adjust buffer weight for a 3–4 o’clock ejection pattern.
Headspace: Always gauge with your chosen .308/7.62 BCG.
Muzzle Devices: Confirm 5/8×24 threads; re-torque and re-zero after installing brakes, flash hiders, or suppressor mounts.
Handguard Fit: Ensure your rail length clears the gas block while allowing access to the muzzle device.
Installation Tips (Non-Instructional)
Prep & Lube: Degrease receiver threads; lightly oil the barrel extension.
Torque Correctly: Follow barrel nut torque specs; verify gas port alignment and secure gas block to spec.
Thread Treatment: Use appropriate thread locker on gas block screws per manufacturer guidance.
Function Check: Confirm ejection, lock-back on empty, and zero with your intended ammo.
Record Dope: After a 100-yard zero, log drops and wind holds for your primary loads.
Care & Maintenance
Routine Cleaning: Nitride makes fouling removal easier—solvent soak, patch, light brush, protect with a thin oil film.
Hardware Checks: Re-check gas block and muzzle device torque after the first range session and periodically thereafter.
Weatherproofing: Wipe exterior surfaces after wet or salty exposure and store dry.
Pair It With
Adjustable Gas Block for suppressed/unsuppressed tuning.
Quality LPVO (1–8×/2–10×) or 3–15× for practical precision and hunting versatility.
5/8×24 Brake or Suppressor Mount to manage recoil and spot impacts faster.
