Your Guide to Buying
In most cases, the price doesn’t matter much to a shopper if he intentionally wants to buy an essential component to upgrade his AR-10 rifle bit by bit. However, budget shoppers have set a ceiling price point that they might want to stick to. This way, they get exactly what they expect.
Therefore, they search for the highest quality and best performance they could afford. Our team suggests that whatever budget you intend to spend for your AR-10 barrel, it is always best to choose one that fits your standard rifle quality. Also, find an AR-10 barrel with the best durability it could offer.
The process of installing these best AR-10 barrels is also an essential factor that you need to consider when buying the best AR-10 barrel. Looking for a barrel for an AR-10 rifle that doesn’t require special tools or a gunsmith to install should be on your list.
If you can find barrels that are easy to install, like a fluted barrel, why should you pay extra cash for it? We have searched for some easy-to-attach barrels, so you can just choose from the list we have provided in this article.
For any gun part or component, having extreme durability that could withstand pressure and any weather conditions is a must. Therefore, we suggest that you search for the best AR-10 barrels made from steel or any high-quality materials that will last you long enough until you finally decide to change for a newer one.
To ensure high-quality durability, you have to search for a new barrel made of really tough stainless steel or chrome-moly steel. These options are highly durable and both rust and corrosion resistant, making the new barrel long-lasting.
Some of the best AR-10 barrels feature a nitride finish inside and out, which makes them more durable. As the barrel technology advanced, some reliable barrels even come with an additional rust-resistant coating.
We always recommend buying the best AR-10 barrels with durable materials to ensure a better performance in the shooting range.
Weight & Length
Typically, AR-10 barrels feature at least 18 to 22 inches in length. And if you are still starting, it is most likely to be recommended to get an 18-inch barrel for your AR-10, as it should be enough for starters like you. While you have different rifle-length gas systems to choose from, like the mid-length gas system, choosing according to your needs, rifle configuration, and intention is always suggested.
The length of your barrel will determine the speed, trajectory, and accuracy of your rifle regardless of the bullet weight. It will also affect the weight of the barrel. The longer the barrel is, the heavier it will become. Longer barrels for an AR-10 rifle may also reduce mobility, making it more difficult to carry the AR-10 weapon. Therefore, if you want to hunt for a longer time, having a shorter barrel would be a better choice for you.
It is also important to know the legal compliance of the best AR-10 barrels you are about to purchase. There may not be many states that restrict the usage of barrels on AR-10 rifles, but it is always better to be sure. Some states restrict semi-automatic rifles based on appearance and would not classify AR-10 rifles as assault weapons. In some states, owning an AR-10 is perfectly legal, though.
Resistance to Rust
Being durable doesn’t always mean it is rust-resistant. Some steel materials may make your barrel sturdy enough to withstand harsh recoil impulse and impacts. However, you have to ensure that the barrel has a special coating made to resist rust to make its life last longer.
We suggest looking for a fluted barrel or a regular carbon fiber barrel that comes with additional coatings, such as Duracoat, chrome-lining, Cerakote, or a nitride-resistant coated finish. These special coatings will not only make the barrel rust-resistant but also corrosion-resistant. It may not mean that it would make the barrel last forever. However, it could help preserve the prime condition of the barrel for a longer period.
Contour & Design
Contour and design don’t only exist for aesthetic purposes. They also affect the performance of your barrel in every meaningful way. For example, a heavier contoured barrel takes longer to heat up and slower to cool all the way off. It could also reduce recoil when shot. The design may also affect the comfort and ease of use of each barrel and its cartridge chamber.
The barrel’s twist rate is also something to look out for, as it greatly affects the barrel’s performance. AR-10 barrels usually come with a twist rate of 1:12, or sometimes even lower, such as 1:7 twist rate bullet rotation. If you use ammo with a standard 168-grain bullet, choosing a barre with a 1:12 twist rate is ideal. However, if you opt to use heavier bullets, you can go for barrels with 1:10 twist rates.
Short barrels blast harder and louder since it is closer to the rifle and closer to the shooter.
Therefore, you’ll need a barrel to reduce the recoil.
Consequently, you also need to look for barrels with a supreme recoil reduction feature if you want to hunt more accurately and have a greater muzzle velocity. Here are the best AR-10 muzzle brakes.
The reduction of recoil may affect the accuracy of the barrel. Therefore, finding the best barrel will definitely improve your shot’s accuracy significantly. Additionally, some barrels offer better accuracy when used in your AR-10 rifles.
Thus, if you aim to focus on this category, you better look for barrels like Faxon Firearms and Criterion Barrels. You may also try to find other options through legitimate hunting or shooting forums that typically share their experiences regarding various barrels.
Our Team’s Selection Process
Our team stands by a selection process to determine the best options we could offer our readers. We always seek to determine the overall performance of the barrels, so we always try them in the shooting range. We schedule a target practice/game or even a hunting game to check the performances of these barrels.
While we also try to research some of the best features of these barrels, we always think that it is better to try them to have the first-hand experience. Therefore, we check their qualities one by one and compare them to the qualities of the other options, such as added features, performance in the shooting range, contour, and accuracy.
Our team also likes diversity, so having a wider array of options for these barrels is always better. We recommend barrels that are compatible with various guns, and not only for the AR-10 rifles. We installed these barrels on various guns to check their compatibility with AR-10 rifles, AR-15, pistols, and any other durable weapon.
The product quality typically lies in the construction of materials used for each barrel. We also considered their special coatings, their ability to resist rust and corrosion.
We also considered the experiences of other gun owners since some barrels’ quality may or may deteriorate when used over time. We researched and reached out to other gun owners through legit forums that openly discuss the quality of these barrels to back up our claims.
Based on our practical experience in the shooting range, the best AR-10 barrel length is 22 inches. Although for small rounds used in your rifle, you can go lower at 20 inches in length. However, if you opt to use magnums, 24 inches is relatively ideal to choose. You can use the same length of the barrel for some weapons.
The effective range of an AR-10 rifle is about 600 yards, just as arguably powerful as the AR-15 rifle. However, this range can shoot tighter groups up to 1000 yards if you use the best barrel for your AR-10 rifle. Thus, our group claims that AR-10 rifles are somewhat better options if you want to shoot targets at longer distances.
Yes, a longer gun barrel improves accuracy. The theoretical accuracy of handguns and rifles is driven by rifling, barrel length, and bullet mass. Thus one can make more accurate shots because the two aligning marks are further, and thus in order to seem aligned to the eye, they have to be “more aligned” than with a shorter barrel.
