Why Builders Choose the BA Premium Hanson .308 (18")

• Hanson profile: Carefully balanced contour that enhances barrel harmonics and handling without excess weight.

• Midlength gas system: Smoother impulse and excellent reliability across a wide range of .308 Win loads.

• Includes low-profile gas block: Precision fit, fewer variables, and a cleaner rail line.

• Black QPQ (nitride) finish: Deeply hardened surface for corrosion resistance, lubricity, and long wear life.

• 4150 CMV steel: Duty-grade alloy chosen for strength, heat resistance, and accuracy retention.

• Threaded muzzle: Ready for brakes, comps, or suppressor mounts (commonly 5/8x24 TPI).

• Premium Series quality: BA’s reputation for sub-MOA potential with quality ammo and proper build practices.

The Hanson Profile Advantage

Unlike traditional heavy or pencil contours, the Hanson profile optimizes weight distribution to reduce whip and improve barrel harmonics. The result is a rifle that points faster, heats more evenly, and maintains consistent accuracy during extended strings—all while keeping front-end weight manageable for positional shooting, hunting, or duty use.

Midlength Gas = Smooth, Reliable Cycling

The midlength gas system is tuned for the 18" format to deliver a softer recoil impulse, reduced parts stress, and consistent lock-back. Paired with the included low-profile gas block, you’ll have a reliable foundation that feeds a variety of .308 Win bullet weights—perfect for a do-all rifle that transitions from range work to field duty.

Built to Last: QPQ + 4150 CMV

Black QPQ (quench–polish–quench) treatment transforms the 4150 CMV surface, enhancing hardness, corrosion resistance, and fouling resistance while maintaining a sleek, non-glare appearance. Inside and out, QPQ supports longer barrel life and easier maintenance—exactly what you want from a premium AR-10 build.

Ideal Use Cases

• Precision Gas Gun Builds: Take advantage of Hanson harmonics and consistent midlength timing.

• Hunting & Field Rigs: Manageable weight and length with excellent downrange performance.

• General Purpose .308: A versatile 18" format is the sweet spot for velocity, balance, and portability.

• Suppressed Setups: Threaded muzzle makes it simple to run brakes or direct-thread mounts; midlength gas helps keep impulse smooth.

Installation Tips (General Guidance)

1. Verify headspace with your chosen bolt; always use proper gauges.

2. Align and secure the included low-profile gas block over the gas port; use high-temp thread locker or pinning per your standard.

3. Torque the barrel nut to spec; confirm handguard clearance over the gas block.

4. Time the muzzle device (if applicable) and confirm concentricity for suppressor use.

5. Function test with quality ammunition; tune buffer/spring if needed for your setup.

If you’re new to barrel installs, consult an experienced armorer or gunsmith. Proper torque, alignment, and gas seal are essential for accuracy and reliability.

Performance You Can Feel

Care & Maintenance

• Clean on a sensible schedule—avoid over-scrubbing; nitrided bores often clean faster.

• Keep the gas block and tube passages clear; inspect for carbon fouling after high round counts.

• Re-check muzzle device torque after heat cycles, especially with suppressor use.

• Lightly oil exterior surfaces after wet or salty environments.
