BALLISTIC BBL 5.56 16″ HANSON W/LPGB

Description

The BA Hanson Midlength is built for shooters who want a capable, lightweight 16-inch carbine that handles a wide range of range and field use without the bulk of a government-profile barrel. Ballistic Advantage’s proprietary Hanson profile removes material where it doesn’t contribute to rigidity, bringing the barrel’s weight down while keeping enough mass at the critical points to maintain accuracy under sustained fire.

The midlength gas system is the mechanical heart of this build’s handling character. Compared to a carbine-length system on a 16-inch barrel, the longer gas tube delays the moment the bolt starts moving rearward, which reduces the sharpness of the recoil impulse and eases the stress on the bolt carrier group over time. For a rifle that gets shot regularly, that matters both in felt recoil and in long-term component wear.

The 1:7 twist rate stabilizes heavier projectiles reliably — anything from 62-grain M855 through 77-grain match bullets will track well. Shooters running lighter 55-grain loads will have no issues, though the twist is optimized for the heavier end of the 5.56 spectrum.

The barrel is machined from 4150 Chrome Moly Vanadium steel and finished in QPQ — Ballistic Advantage’s corrosion-resistant treatment that hardens the surface and provides protection comparable to chrome lining without altering bore dimensions. The Nickel Boron coated M4 feed ramp extension reduces friction at the chamber entrance and wipes clean easily. The .625-inch gas block journal carries a pinned low-profile gas block from the factory. This barrel is not compatible with aftermarket piston conversion kits, so it’s intended for standard direct-impingement builds only. The muzzle is threaded 1/2×28 for standard AR-15 muzzle devices.
