This 5.56 chambered 10.3 inch Performance Series Barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish. Our performance series barrels feature a Nickel Boron Coated Extended M4 Feed Ramp Extension.

Hanson Series Barrels feature our proprietary BA Hanson profile and include a pinned lo-pro gas block. Hanson barrels are not designed to work with aftermarket piston kits.

“The original BA Hanson profile barrels have a .750” diameter at the gas block journal and it is more of a light/medium contour. The BA Hanson .625” barrels are called this due to .625″ diameter at the gas block journal. This profile is a thinner and lighter weight version of the original BA Hanson profile. Each BA Hanson barrel comes with a pinned, lo-pro Gas Block already installed which makes them an excellent value.”

No better bang for the buckReview by Bill
I've ran a lot of AR's. There is no better handling , faster pointing barrel on the market . Packed with features found on barrels costing much more. I run this barrel hard and like to do drills on steel gongs all CNS sizes and smaller....don't let the thinner profile of this barrel scare you . For doing what a barrel like this is really meant for it will run true and hit after hit after hit it performs in a fast dynamic environment. It cools fast , I run a SLR Solo and it vents well so as long as its getting good air it doesn't heat up to the point of being uncomfortable ....unless your truly just making noise and wasting ammo.....cant help you there but running hard in drills this barrel is a dream and its a first grab fighting gun (Posted on 2/17/2018)
Awesome barrel AND Company!Review by Randall
When my brother asked me to build an AR for him, I chose B.A. for the barrel, and Im glad I did. I was so impressed with the barrel, since then I've bought three others for myself and will continue to use them exclusively in my builds. I could speak all day on the barrel itself but since that's already obvious and in other reviews, I want to use this review to thank B.A. for their EXCELLENT customer service. I bought this barrel at the end of a sale they were having. This barrel was at an unbelievable price and I added to my cart. When I added to my cart it was showing the sale price on the page but during the time I let it sit in the cart, the sale had ended. Being in that weird transitional period, it showed the regular price in my cart, while still showing the sale price on the page. I took a pic of the page and went ahead with the purchase, paying the full price. Then I emailed them, explained the issue, and respectfully requested a refund on the difference not really expecting anything knowing the could technically deny since I already made the purchase at the full price. They emailed me back saying it was no problem and they sent me a refund of the difference back to my card!! No questions asked. They didn't have to do that and now I am a grateful lifelong costumer. No wonder they are as successful as they are. Costumer service does not get any better and you can not go wrong with B.A.! Thank you!!! (Posted on 1/4/2018)
Nice profileReview by Dennis
Picked one of these up from a different vendor for a pistol build. I have no complaints with the barrel and it's profile seems to balance the gun nicely.

Gas port seems to be sized appropriately for the length - running an H2 buffer it cycles everything I can throw at it. I'm sure other buffer weights would work just as well but I haven't had a reason to change mine.

Gas block is pinned and features two set screws, set screws are not dimpled. Gas block was straight prior to pinning and aligned perfectly with my receiver.

Given my experience, I'll likely buy an 18" Hanson for my next build. (Posted on 7/9/2017)
Great barrel from a great company.Review by Gregory
Finally got a chance to shoot this barrel today, being it is my second BA Hanson barrel I had high expectations... It did not disappoint. 1 MOA or better depending on my shooting.

On a side note... The customer service they offer is awesome. Had an issue awhile back and Clint H himself called me to address my issues. (Posted on 4/24/2017)
Simply SpectacularReview by Christopher
We run an 11.5 in govt profile barrel in our work guns and they are, well, they are accurate enough for government work. I wanted a personal upper in the 10inch-ish range mainly to use suppressed but also be a kind of do anything gun. Ordered the 10.3 inch Hanson profile barrel (with .625 gas block) and had it to my door in two days. Barrel looked great, the NiBoron barrel extension is a nice touch. Fit and finish far exceeded my expectations for a barrel and gas block combo that came in right at $200. (I've purchased barrels in the $300-400 range that didn't look as good) The barrel fit quite snugly in a RRA upper. Assembled it with a 9 inch Midwest Industries upper and barrel but, and topped it off with a silencerco flash suppressor. The gun functioned flawlessly. I'm utilizing a H2 buffer and a fairly stiff wolf buffer spring with an FN bolt and carrier. Ballistic advantage offers a sub MOA guarantee with their barrels. Using match ammunition of course. Well I grabbed some 69 grain SMK and some 77gr MK262 mod 1 (basically Black Hills 77gr Match) to test that out. I never got to it. The Winchester 62gr OTM (which is NOT a match round despite its name) that I used to do the break-in procedure and function testing produced a somewhat elongated one hole three shot group. Granted this was at 50 yards. I didn't have time to get back to 100yards but that group is easily under an inch at 100. I used a fixed 4 power Acog and a wobbly grip-pod as a bipod. I'm now dying to know what it will do with a decent scope and a bipod and sandbag with match ammo. Lastly, I had some concern about how much point of impact shift I would have hanging a somewhat chunky silencerco Hybrid off the end of that skinny and light barrel. The answer is less than a quarter of an inch at 50 yards. I don't think I've ever been more pleased with a firearms related purchase. I'm seriously bummed I have to carry my crappy-in-comparison issued rifle at work instead of this one. (Posted on 4/11/2017)
