7 Best AR-10 Barrels: Our Favorites For Builds

Looking to build a new AR-10? We cover the different patterns, interchaneability with the AR-15, and our favorite AR-10 barrels for accuracy and budget.

If you’ve built your own AR-15, and it just wasn’t enough for you, you may be looking for something even bigger and better to try your hand at.

If so, the AR-10 is calling your name!

The AR-10 isn’t as modular as the AR-15, but it is trending that way.

While the AR-15 and AR-10 can share some parts, one thing they can’t share is their barrels.

The barrel of your gun is incredibly important, but you know that.

Sure, it can determine the velocity of your ammo, the accuracy of your weapon, but it can also change how the gun handles and even the legality of the gun.

Let’s look at a few diverse barrel options and talk about why, who they’re for, and where you can get them.

The AR-10: Big Brother to the AR-15

Do you guys remember that show Tool Time with Tim Allen? It was a staple of my childhood and the main character’s catchphrase was always “More power!”

I bring all this up because for some reason I can’t help but picture Tim Allen screaming MORE POWER when describing the AR-10.


In reality, the AR-15 is the AR-10 with less power because the AR-10 came first.

The AR-10 was the original Stoner Armalite design and was a product of its time. The full-powered battle rifle was still the NATO standard for weaponry, and the powerful 7.62×51 was the round to rule them all for infantry rifles.

The AR-15 has always been a bit more popular with everyone. Militaries, police forces, and civilians all love the AR-15, but the AR-10 is starting to get some love.

A lot of guys have built or bought AR-15s en masse and are beginning to look at the bigger brother for something new.

This is especially true with the success of rounds like the 6.5 Creedmoor and the rise in long-range shooting (see our reviews for the best precision sniper rifles for beginners!).

The Many Patterns of an AR-10

AR-10s are tricky animals.

They have two different patterns — which essentially means two different ways to build a gun via magazines, receivers, etc. The two patterns are the DPMS and Armalite.

The DPMS pattern is way more common and likely takes up 90% of the AR-10 market. These rifles have cheaper magazines, a ton of different manufacturers producing receivers, and tons of different parts.

For that reason, I could only find barrels for DPMS guns across the market. The oddball Armalite pattern is here or there, but I doubt many people use the pricier, and harder to find Armalite pattern. So keep that in mind when shopping for any AR-10 pattern part.

We’ve rounded up a collection of our favorite options for just about every budget and need. You’re pretty sure to find something that will work great for you and your AR-10.

Let’s take a closer look.

Best AR-10 Barrels

1. Palmetto State Armory

So this is a two-in-one category because the AR-10 is most popular in two calibers: the .308 and now the 6.5 Creedmoor. Regardless of which caliber you choose, a budget option should be on the table.

I went with Palmetto State Armory, and if you’ve done anything with ARs, you know their name. They make a variety of different guns, and they often do it at a great price. These are great for a first AR-10 or if you are on a tight budget.

PSA AR-10 .308
PSA AR-10 .308

The two barrels are, of course, very similar in design and the material used. They are both made of stainless steel, which will enhance accuracy a smidge. Of course, stainless steel will wear out sooner, but are any of us going to shoot a barrel out?

We aren’t Daniel Horner, so I’m sure stainless steel will work fine for our applications. The barrels are also a heavy-profile, rifle-length 20-inch design. They are, of course, threaded so you can top it off with whatever muzzle device you choose.

The PSA 20″ 6.5 Creedmoor barrel has a 1:8 twist rate, so you stabilize rounds in the 139 to 142 grain well. This barrel sells for a hair over $200. We’re a big fan of the PSA 6.5 Creedmoor upper, which includes this barrel — check out our review on it!

The PSA 18″ .308 Winchester variant has a 1:10 twist rate so your most common .308 projectiles will be well served. This barrel sells for less than $200 and it’s a steal at that.

2. Faxon Match Series

Do you want to build a gun capable of hitting the hat off a mockingbird at 100 yards? We got you covered!

Well, not us, but Faxon Firearms has you covered with their match series, 20-inch, heavy fluted barrel.

The Faxon Match Series barrel is a very heavy-duty design, and one made for those demanding a high-quality barrel without worrying too much about the cost. While this isn’t the cheapest barrel, you are getting a lot for your money.

The barrel fluting will help reduce weight and the 20-inch, stainless steel barrel weighs only 2.4 pounds — which is very nice. The barrel is 416-R stainless steel, which makes it a better option for precision shooting.

Faxon Firearms Match Series- 20" Heavy Fluted, .308 WIN AR-10 Barrel
Faxon Firearms Match Series 20″ Heavy Fluted, .308 WIN Barrel

The rifle has a salt bath nitride finish and is button rifled with a 1:10 twist rate. The barrel is a magnetic particle inspected and sports an 11-degree polished target crown. The fluting not only reduces weight but does helps the barrel cool a bit faster between strings of fire.

The barrel extension is DPMS LR .308 compatible and has a nickel Teflon-coated finish. It’ll last just about forever in the most common AR-10 platform out there.

Faxon has created an excellent barrel for those looking to build a high-powered, accurate, semi-automatic gun in the traditional, hard-hitting .308 Winchester. It’s almost a shame to put a handguard over it with it being as pretty as it is.

3. BSF Carbon Fiber Barrels

Did you catch yourself thinking that Faxon barrel is nice, but I want something lighter, and maybe a little pricer?

Perhaps you thought you could make a fun “Flex on the Poors” post over at r/guns and get some invisible internet points? Or maybe you just like the cutting edge of barrel technology and want to get your hot little hands on it?

Well, you can have all three with a BSF barrel. These barrels utilize the always excellent 416R stainless steel underneath a carbon fiber sleeve. The mix of both steel and carbon fiber creates a durable, but lightweight barrel capable of excellent accuracy.

BSF uses a jacketing method rather than a wrapping method. They claim wrapping can trap heat and cause delamination.

Their carbon fiber is designed to expand at the same rate as 416R stainless steel. There are also slots milled in the carbon fiber which will allow air to reach the barrel and help it cool.

These barrels are available in both .308 and 6.5 Creedmoor for the AR-10. The lengths vary from 16 to 24 inches, and the barrel can be had fluted to reduce even more weight. The choices are expansive, but so is the price so beware of that.

Admittedly these are perfect for a Gucci AR-10 build. These barrels are only DPMS compatible.

4. Aero Precision .308 Barrel

Aero Precision is a fantastic company that makes some tremendous rifles, and rifle components. Aero Precision makes a ton of different barrels, but I chose one that is a little different from what we’ve seen on this list so far.

We’ve seen a lot of stainless steel barrels, so let’s mix it up and add an excellent CMV barrel.

CMV stands for chrome moly vanadium and compared to stainless steel its a little less accurate, but a lot stronger. The 16-inch barrel makes it as short as it can be to be a title 1 rifle. The CMV barrel makes sense when it is only 16 inches long.

A 16-inch barrel isn’t designed for superbly long range. As a carbine, the gun will likely see more rounds fired rapidly at close range. CMV barrels will last nearly forever, and your gun will run longer than you’d expect.

Aero Precision 12.5" .308 CMV Carbine Barrel
Aero Precision 12.5″ .308 CMV Carbine Barrel

The Aero Precision .308 barrel has a QPQ finish to keep a high level of corrosion resistance and to shrug off the rust.

The Aero Precision barrel is also tested to an extreme, and this includes a high-pressure test followed by magnetic particle inspection to looks for cracks and damage not visible to the naked eye.

Aero Precision makes barrels for both the 6.5 Creedmoor and the .308 AR-10 barrels in a variety of lengths, but 16 inches combined with a CMV steel makes this a mighty close-range sledgehammer.

The barrel is threaded, sports a 1:10 twist rate, and has a heavy contour to it.

5. Wilson Combat Super Sniper

Wilson Combat is known for making some of the most excellent firearms on the market.

From their finely tuned 1911s to their always excellent shotguns, they do a bit of everything. The Wilson Combat Super Sniper barrel lives up to its reputation of being just fantastic.

The Wilson Combat Super Sniper barrel is best found in 6.5 Creedmoor and is purposely built to shoot longer and heavier rounds. These rounds are what is commonly used in long-range shooting.

The barrel is made from stainless steel and has a 1:8 rifling twist rate. The rifling is a right-hand twist and is precision button rifling.

The Super Sniper is a long 24 inches, but it maximizes the 6.5’s velocity and allows the shooter to reach out and touch their target. The barrel is long and made of stainless steel so you can expect it to be massive.

Wilson Combat Urban-Super-Sniper1190
Wilson Combat’s Urban Super Sniper AR-10 build

To help a little with this weight the barrel is fluted. It still tips the scales at 63 ounces. However, if you are shooting long-range targets, you are likely in a prone position, and this isn’t a big deal. This barrel is designed to be as accurate as possible.

This is the go-to option for reaching out to 1,000 yards with consistency. This will undoubtedly give you an edge for hitting targets far away and producing teeny tiny groups. Wilson Combat also does a body good, or a receiver good, and they don’t slack here.

6. Ballistic Advantage 12.5 .308 Tactical Government Carbine

Oh my…who doesn’t want an AR-10 with a 12.5-inch barrel? Seriously? It’s a tiny powerhouse that is perfect for an SBR or a pistol build.

I know what you are thinking…a 12.5-inch AR-10 in .308 seems mighty uncomfortable.

Available Coupons

Well admittedly it’s not as smooth as a 24-inch barrel, but it is entirely controllable. I had some time with a 12.5-inch barrel at a SHOT Show Range Party, and it was quite comfortable with a good muzzle device.

Even with a linear comp, the flash is still pretty damn bright — but, man, is it cool.

The Ballistic Advantage 12.5-inch barrel is a 4150 Chrome Moly Vanadium barrel that will resist the heat and pressure put on it by tons and tons of rounds fired downrange. With a barrel this short you have a fun build, and I’m sure you’ll be putting plenty of rounds downrange.

Ballistic Advantage 12.5" .308 Tactical Government Carbine AR-10 Barrel
Ballistic Advantage 12.5″ .308 Tactical Government Carbine AR-10 Barrel

The Ballistic Advantage 12.5-inch barrel also has a QPQ finish for increased corrosion resistance and a nice strong finish. This little fellow is an interesting choice and will allow you to maintain a compact rifle when using something like a suppressor.

Other than that you’ll have a compact gun that is quite fierce in a very light and small package. I can’t think of a use for a .308 with a 12.5-inch barrel, but this is America! Let freedom (and your ears) ring!

Otherwise BA does have some nice 6.5 Creedmoor barrels recently as well.

7. Criterion Barrels

If you need the best precision for a price that won’t buckle your knees, Criterion is one of our top picks.

While the extra’s on David’s rifle has gone through some changes, the Criterion barrel has been outstanding from the first shot.

Getting sub-MOA with an AR-10 isn’t nearly as easy as the cherry-picked groups you’ll see online might lead you to believe. The fact is that gas rifles need a lot of great parts to work together perfectly to produce truly accurate rifles.

Several factory loads are sub-MOA with this rifle and most of that is due to having a great barrel.

The AR-10 is an excellent gun.

With modern parts, accessories, and manufacturers we are seeing the AR-10 rise from the ashes. What was once considered heavy and cumbersome is quickly becoming the handiest option for a full-powered semi-automatic rifle.

The AR as a platform is extremely easy to modify and change, like its younger sibling, the AR-15, and one of the most significant components is the barrel.

The choice of a barrel for your build is a significant one, and you choose a barrel based on your needs. Long-range, close-quarters shooting, and hunting all have different needs, so choose wisely.

    So how much can you really improve accuracy of an AR-10 with the barrel? Your article suggests AR-10s are finicky and seems to say barrel alone isn't the only factor. For example, the Pew Pew write up on Aero Precision M5 doesn't seem to give it a consistent sub moa or even moa performance. If you take that same aero build and put on a different barrel, would you confidently say it would become sub moa?

      You are correct Stephen and thank you for the info. I would not have looked as I thought all Aero parts including barrels were made in house. Found the following in their FAQ's

      Q. Do you make your own components in house?
      A. We manufacture most parts in house, including upper receivers, lower receivers, handguards, scope mounts, and various other pieces. Our barrels are manufactured at our partner company Ballistic Advantage.

      I recently built an AR-10/SR-25 in .308 with all Aero parts. 18" CMV (Stainless was a little difficult to find at the time). I added a Luth-AR stock and a Magpul MOE. Everything else 100% Aero. Only have done a rough zero with 6 rounds (time and ammo constraints at the time). Need to do my part and try some different ammo as well. Looks promising. Here's to hoping but not opposed to switching out if needed or a second upper hell, eventually maybe three. Two - .308 (18" CMV maybe 20" Stainless) and one - 6.5 (24" Stainless). I'll start saving for those now and the ammo too.

    I understand putting Criterion on here, and even the BSF. But why is every article on parts seem to be based on budget builds? Do they sponsor these articels? No mention of krieger, Bartlien, Douglass, rock creek, brux, lother walther, literally any top 10 barrel maker. Yes they are somewhat expensive, but no more than the BSF.

    I have a 24" Criterion barrel chambered in .308. I paired it with all Aero Precision parts that include a Magpul PRS stock and JP Silent Captured Spring and finally a Superlative Arms tuneable gas block and that rifle is simply the softest shooting and most accurate Rifle I have ever seen! Much less shot! Super Impressed! It definitely out-shoots me haha

    I wouldn't be so quick to say CMV barrels will outlast stainless... I have 3000+ rounds through an 18" Aero CMV barrel and groups are starting to open up. Another strange thing was how much jump it has before the rifling and this was from day one. Monitoring the wear shows that the jump is getting longer too... Pretty sure that is the reason for accuracy falling off. I really want a Wilson Combat barrel for my 308, have two Wilson's in smaller AR's, a Blackout with over 10K through it and a 7.62x40WT with 5500 down the tube and both of those are still sub moa guns.

    I'm surprised you didn't mention the Proof Research carbon fiber barrels. Admittedly, I was disappointed and underwhelmed with the accuracy of my build using the Proof 20" with +2" gas system, Aero Precision M5 lower, Geissle trigger, JP BCG and high pressure bolt, and Radian Raptor handguard in 6.5 Creedmoor. My bolt gun in 6.5 Creedmoor shoots light out (0.2-0.3 MOA) with the Christensen Arms carbon barrel on a glass bedded Rem 700 action, but the Proof/Aero not so much. I expected 1/2 MOA but could only muster 0.7 or so, and not all the time. Typically around 1 MOA was the norm, even with my best handholds, and no better than a $250 Ballistic Advantage barrel with standard rifle length gas system. I expected much better accuracy considering the $800 price tag of the Proof Research barrel. It ran perfectly, just not as accurate as I had hoped.

      CF wrapped barrels have a number of issues with them. Unless you're looking for a low rate of fire, ultra-lightweight barrel, CF wrapped is not a great choice generally. Proof Research is one of the leading names in CF barrels and even theirs can be hit and miss, which is mostly due to the nature of CF wrapping. Because of these reasons we really don't recommend them except for niche cases.

    I got the 18" wilson combat super sniper for my aero precision m5e1 and I love it. I did have to open the gas port with a 3/32 bit because i had it armor coated and i think some of it got in to the gas port. But after that it runs beautifully! I dont regret that purchase at all.

    Check the weight on the carbon fiber barrels. There are options that are just as light and promise the same accuracy for half the money. Faxon big gunners are affordable and very light. I have one in 308 and like it. I ordered a 24 inch Faxon heavy fluted 6.5 cm today. I thought I would buy a carbon fiber but they weren't lighter, just costlier.

      Check the diameter on the carbon fiber barrels. You are getting a heavy barrel profile with all the benefits of a heavy barrel while being lightweight. Skinny pencil barrels heat up fast and don’t perform as well. With carbon fiber you get the best of both worlds.

      Not to mention the chambering on the BSF barrel is not QAd so they are so far out of range that they shoot 2.5-6in minutes! I can't believe they even recommended these without trying them...they are an EXPENSIVE piece of terrible!
