Best AR-10 Barrels: AR-10 Barrel Guide

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

Your barrel can determine the velocity of your ammo and the accuracy of your weapon. It can also change how the gun handles and even the legality of your firearm.

Let’s look at a few of our favorite barrel options and talk about why you'd pick one over another, who they're for, and where you can get them.

Do you want to build a gun capable of knocking 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. 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 416R stainless steel, which makes it a good option for precision shooting.

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 helps the barrel cool a bit faster between strings of fire.

The barrel extension is DPMS LR .308 compatible and has a nickel-Teflon finish. It’ll last just about forever.

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.

If you are looking for the absolute best barrel on this list, it's right here with the JP Enterprises Supermatch.

These are top-of-the-line 416R stainless steel barrels that are lead-lapped, button-rifled, air-gauged, and then cryogenically treated. All of this means that you will have better consistency from your very first cold-bore shot all the way to your last.

And if that isn't enough, each Supermatch barrel includes an individually matched and headspaced JP Enhanced Bolt. This takes out any of the guesswork when it comes to making sure your bolt and barrel are working to get you the most out of your gun.

JP Enterprises is sitting near the top of the heap when it comes to everything AR these days, and their barrels are no exception. These are in the same league as barrel offerings from companies like Bartlein, Shilen, LMT, and other high-end manufacturers.

3. Palmetto State Armory AR-10 Barrel / BCG - Best Budget

Specs

• Caliber: 6.5 Creedmoor
• Barrel Length: 20"
• Profile: Heavy
• Material: 416R stainless steel
• Twist: 1:8
• Gas Length: Rifle

Palmetto State Armory makes 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. For those looking to try out 6.5 Creedmoor instead of the more standard .308, a cheaper option to dip your toes in the pool is never a bad thing.

The barrel is made of stainless steel, which will enhance accuracy a smidge. Of course, stainless steel will wear out sooner, but not everyone is Daniel Horner, so I’m sure stainless steel will work fine for most applications.

PSA offers their 6.5 Creedmoor barrel in a heavy-profile, rifle-length, 20-inch design. They are also threaded so you can top it off with a muzzle device of your choice.

It 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, or you can snag the combo that includes a BCG for $350. We're a big fan of the PSA 6.5 Creedmoor upper, which includes this barrel.

Specs

• Caliber: 6.5 Creedmoor

• Material: Stainless steel
• Twist: 1:8
• Gas Length: Rifle

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

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

The AR-10 is an inherently accurate platform, and sub-MOA groups aren't uncommon. However, a tuned gas system and a quality barrel can really push the accuracy envelope of the platform. Getting half-inch groups or less at 100 yards isn't unheard of for a well-equipped AR-10.

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

Oh, my. Who doesn't want an AR-10 with a 12.5-inch barrel? 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 seems mighty uncomfortable to shoot.

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 no problem 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.

It 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.

Ballistic Advantage is known for its outstanding performance for the price. They make barrels for many other companies, including their sister company Aero Precision. This barrel will get you a compact gun that is quite fierce in a very light and small package, all at great value.

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

5. Wilson Combat Super Sniper - Notable Mention

Notable Mention

Wilson Combat Super Sniper

$334 at OpticsPlanet

AR15 Discounts (see price)

Specs

• Caliber: 6.8 SPC
• Barrel Length: 24"
• Profile: Recon tactical (similar to medium)
• Material: 416R stainless steel
• Twist: 1:11
• Gas Length: Mid

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.

Wilson Combat's Super Sniper barrel is purposely built to shoot longer and heavier bullets commonly used in long-range precision 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.

It is a long barrel at 24 inches, but it maximizes 6.8 SPC’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 a beast.

While the barrel is fluted, it still tips the scales at 63 ounces. If you're shooting long-range targets, you're already in a supported position, so 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.

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. Full-powered battle rifles were still the NATO standard for weaponry, and the powerful 7.62x51 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 see a resurgence.

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.

For the most part, there are two different patterns, DPMS and Armalite. This essentially means there are two different ways to build a gun via magazines, receivers, etc.

The DPMS pattern is way more common and likely makes up about 90% of the AR-10 market. DPMS patterned rifles have cheaper magazines, a ton of different manufacturers producing receivers, and a much wider aftermarket.

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. Keep that in mind when shopping for any AR-10 pattern part.

Final Thoughts

The AR-10 is an excellent gun.

With modern parts, accessories, and more manufacturers, we are seeing the AR-10 continue to rise in popularity. 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. Long-range, close-quarters shooting, and hunting all have different requirements, so choose one that best fits your mission.
