Description
Ballistic Advantage built its reputation on barrels that punch well above their weight, and this 13.7-inch Performance Series in 5.56 NATO is a great example of why builders keep coming back. It's cut with the signature BA Hanson profile, which ditches the traditional right-angle shoulder at the gas block journal and instead tapers smoothly toward the muzzle. That shoulder-less design trims weight and helps reduce barrel whip, so you get a nimble, front-light feel without giving up the rigidity you want for accuracy.
Underneath the profile, this is a serious piece of steel. It's machined from 4150 Chrome Moly Vanadium and finished with a QPQ nitride treatment inside and out, which fights corrosion and holds up to plenty of rounds down range. The 1:7 twist stabilizes heavier bullet weights nicely, making it a versatile pick for everything from cheap 55-grain range ammo to heavier defensive and match loads. Extended M4 feed ramps with a Nickel Boron coating round out the package and keep rounds feeding smoothly.
Why the 13.7-Inch Hanson Barrel Hits the Sweet Spot
The 13.7-inch length paired with a carbine-length gas system is a favorite for folks who want a short, maneuverable AR without dropping all the way down to a stubby SBR barrel. You still get respectable velocity and reach, but the whole rifle handles quicker and points faster. With a permanently attached muzzle device bringing it to 16 inches, this length is popular for a reason.
What Comes on This Ballistic Advantage 5.56 Barrel
One of the best parts of the Hanson Performance Series is that it ships with a pinned low-profile .750 gas block already installed. Builders consistently mention how much that simplifies the job since the gas port alignment is handled at the factory. Drop it in your upper, install your handguard and muzzle device, and you're most of the way to a running rifle. Note that Hanson barrels are set up for direct impingement and aren't designed to work with aftermarket piston kits.

Frequently Asked Questions
Does the Ballistic Advantage 13.7" Hanson barrel come with a gas block?
Yes, it ships with a pinned low-profile .750 gas block already installed at the factory. That takes the guesswork out of gas port alignment, which is one of the trickier parts of a barrel install. Builders regularly point out how much smoother this makes getting a new rifle up and running.
What twist rate is this barrel and what ammo does it shoot best?
It has a 1:7 twist, which is well suited to stabilizing heavier bullet weights. That makes it versatile enough to run everything from budget 55-grain plinking ammo up through heavier 62 to 77-grain defensive and match loads. It's chambered in 5.56 NATO, so it will happily shoot both .223 Rem and 5.56.
What is the BA Hanson profile and why does it matter?
The Hanson profile removes the traditional right-angle shoulder at the gas block journal and tapers the barrel toward the muzzle instead. This trims weight for a lighter, faster-handling build while the continuous diameter helps reduce barrel flex for better accuracy. It's a popular middle ground between a heavy profile and a thin pencil barrel.
Can I use this barrel with a piston system?
No, Hanson barrels are set up for a standard direct impingement gas system and are not designed to work with aftermarket piston conversion kits. If you're running DI like most AR-15 builds, you're good to go. Pair it with a quality bolt carrier group and carbine buffer setup for reliable cycling.
