The Ballistic Advantage Performance Series of barrels offer a ton of improvements over standard offerings. This 13.9” AR-15 barrel is chambered in 5.56 NATO and features the lightweight Hanson profile. It is made from 4150 Chrome Moly Vanadium steel with a durable and slick QPQ salt bath Nitride finish for long term corrosion resistance while the barrel extension features a Nickel Boron coating. The M4 feed ramps are a high wear point and the harder Nickel Boron will stand up to thousands of rounds rubbing against it. The mid-length low profile gas block comes from the factory pre-installed and pinned for a rock solid and reliable setup. The 1:7 twist rate helps to stabilize heavier rounds especially out of a barrel this short. Threaded 1/2x28 for all your favorite muzzle brakes, so you can launch fireballs down range. High pressure tested, and magnetic particle inspected, this Ballistic Advantage 5.56 barrel is great for building your next carbine.

2.1” shorter than 16”

Great barrel for pin & weld. Pinned gas block makes alignment easy for gas block. Much lighter than the gov profile 16” I had on before

Barrel looks perfect & more accurate than me

by -

High quality barrel with gas block. Easy to remove gas block (2 hex screws) to install barrel nut & gas tube. Exactly what I needed and happy to catch it on sale. Thank you

I love these barrels

I've built 4 rifles with these barrels now. They are high quality, great finish, super accurate, and the pinned gas block is a BIG step saver that makes the build convenient and reliable. This is an outstanding product.

I purchased this barrel and was amazed at the shipping that Primary Arms did, it was shipped the same day. The quality is tremendous, it will make a nice lightweight build

Great Barrel

Quality barrel as always from BA. For the price you'd be hard pressed to find better barrels than the ones from BA. I have several of them and have been happy with all of them.

I like it! Butt...


Nice barrel! Everything you want in a barrel.
Except, I've been experiencing short stroking. After check my gas block alignment, I gave it a go. Still short stroking. I was using Tula Ammo. Haven't had the chance to use anything else.

Excellent barrel

I am officially a Ballistic Advantage fan boy. Easy install, fit and finish is superlative, accuracy is outstanding.

Top Notch

Very high quality barrel. I have between 400-500 rds through it so far. Using a spikes st-t2 & a V7 Teflon coated carbine spring it cycles perfect & kicks brass at 3 o’clock. Super accurate with 55’s-77’s. Definitely on par with the more expensive options. I’d highly recommend!
