Why Choose This TacFire .308 Barrel?
20" Sweet Spot for .308: Extra dwell time and velocity over carbine/18" barrels for flatter trajectories and more energy on target—ideal for big-game and steel out to distance.
Black Nitride Finish: Ferritic nitrocarburizing on the bore and exterior resists wear, heat, and fouling—clean-up is faster and less abrasive.
AR-10/DPMS Pattern: Built around common large-frame AR specs for straightforward integration with quality receivers and handguards.
Accuracy-Minded Construction: Rigid 20" profile supports consistent harmonics for repeatable groups with quality match or hunting ammo.
Long-Term Value: Nitride treatment extends service life, helping maintain precision over high round counts.

Compatibility & Build Notes
Receiver Pattern: Match with DPMS/LR-308-pattern uppers/handguards and SR-25 magazines.
Gas/Buffer System: Pair rifle-length gas (if applicable) with a .308-specific buffer and spring; tune buffer weight for a 3–4 o’clock ejection.
Muzzle Devices: If using brakes or suppressor mounts, verify 5/8×24 and re-torque; re-zero after installation.
Headspace: Always check headspace with your chosen .308/7.62 BCG.
Handguard Clearance: Ensure your free-float handguard length leaves proper access to the gas block and muzzle device.
Installation Tips (Best Practices, Non-Instructional)
Prep & Lube: Clean receiver threads; lightly oil the barrel extension.
Torque Correctly: Follow manufacturer torque specs for barrel nut; confirm gas block alignment with the gas port.
Secure Fasteners: Use proper thread treatment on gas block screws (per mfr guidance).
Function Test: Verify ejection pattern, lock-back on empty, and zero with your intended ammo.
Record Dope: After zeroing at 100 yards, document drops/wind for your preferred bullet weights.
Care & Maintenance
Routine Cleaning: Nitride simplifies bore care—solvent soak, patch, light brush as needed, then protect with a thin oil film.
Fastener Checks: Re-check gas block screws and muzzle device torque after the first range session and periodically thereafter.
Storage: Lightly oil the exterior and store in a dry environment to maintain the finish.
