One way to up your paintball prowess is upgrading your marker’s stock barrel. While the stock barrel performs okay, aftermarket barrels have better efficiency, sound signature, and improved accuracy.

However, you cannot just pick any barrel on the market. First, the barrel must be compatible with your marker, which is determined by the type of thread. The only option to utilize an incompatible barrel is using an adapter which will be an additional expense.

The other considerations include the length, bore size, and material. Whether you want a one-piece or a set of barrels, I have something for you.

In this article, I have compiled the best paintball barrels for a wide range of markers. I have also covered in-depth what to consider when picking one.

Frequently Asked Questions

How to Choose a Paintball Barrel

Purchasing the right paintball barrel means having a successful and fun day out on the paintball field.
There are many factors you need to consider when choosing the best one for your marker. Understanding what to look for in a paintball barrel gives you the knowledge necessary to buy the right product.
Here are some helpful tips on how to choose the best paintball barrel


Paintball guns utilize different types of threads. Threads are the grooves connecting the barrel’s front end to the paintball gun.
Here are the commonly used threads by many guns:
– A5
– Autococker
– 98 customs
– Ion
– Shocker
You buy an excellent gun only to find out the barrel isn’t compatible with what you need or want. We’ve all been there. If you know what kind of threading system you need before you buy a paintball gun, then you can avoid all those messes.

The Material 

Paintball barrels come in a few different styles and sizes, as well as materials. When you choose your paintball barrel, your decision should be based on the material of the barrel as well as how the barrel will be used.
The most common material for paintball barrels is aluminum and carbon fiber material. Why? Aluminum is inexpensive and has some inherent advantages over other materials. Fiberglass is another popular choice for many paintball players.
It not only looks good but also makes the gun lighter which can make it easier to carry all day long. Let’s discuss the commonly used materials in detail.


Aluminum barrels have popped into the paintball world over the last few years. These barrels are affordable, lighter than traditional steel barrels, and provide great accuracy.
The downside of aluminum paintball barrels is that they dent easily when put under extreme pressure.

Carbon Fiber

Carbon fiber barrels are often made from a high-strength weave to give them plenty of strength. The high-strength weave ensures that the barrels will function perfectly even when hit with a paintball at 400 FPS.
The only downside to using carbon fiber is that it’s usually about twice as expensive as other types of materials. If price isn’t an issue, then I’d suggest you get one of these carbon fiber paintball barrels.

Stainless steel barrels

If you want the best possible muzzle velocity out of your paintball gun, stainless steel is the way to go. Stainless barrels are far more durable than other options. If you’re worried about one of your teammates crushing your barrel this is probably the safest choice.


Companies have proven that brass is better for producing high-end barrels.
The problem with brass is that it’s not very good for the bottom line, as it costs more
So, what material should you use for your next paintball barrel? This isn’t nearly as complicated because it only really depends on your situation. If you’re new to the game and buying your first gun, a carbon fiber barrel is a great starting point.
If you already have a good quality pump/semi-auto marker, then I would recommend going with stainless steel. It will last a long time and not warp from getting too hot from rapid firing.


Figure out how long your gun’s marker’s original paintball barrel is. Ideally, the new aftermarket barrel will be slightly longer than the paintball gun’s stock barre
The right paintball barrel length will depend on the gun you’re using, the range you plan to shoot from, and your personal preference. It’s important to take all these factors into consideration before you make the buying decision. However, if you’re looking for optimal accuracy, your paintball barrel should be 12 to 16 inches. But if minimizing sound signature is important to you, don’t go much higher than nine inches.

Bore Size

The correct bore size is important to get right. A barrel that is either too small or too large may not provide the best functionality for your marker. Since you’ll be constricting the paintball’s range of motion. If you want more accuracy or efficiency out of your gun, your barrel should match the bore size of your barrel perfectly. If you are want to try different paintball brands go with a kit that has a set of replaceable inserts.

Sound Signature

Sound signature and noise level are a big deal in the world of paintball. It’s often one of the first aspects players note when talking about markers. That’s because the barrel length, bore size, porting, and other features can all affect how loud or quiet a marker is when firing. It’s something worth keeping in mind when shopping for upgrades.
Make sure you get features that work well with your play style and field requirements. You should choose a paintball barrel that properly matches your needs and playstyle. If you want to reduce the shot sound of your marker, get a silenced paintball barrel.
But if your goal is more about accuracy and range, get a standard bore or one of the faster upgrade barrels. You’ll see less of a performance boost with an upgraded barrel than if you upgrade the other components on your marker. Upgrading your barrel can put you at an advantage in the field.


It’s true that there are many paintballs barrel options out there, and finding the right can be difficult. Put simply, the review above is intended to help you make an informed decision on where to invest your money. The bottom line is to look for a lightweight barrel, that will help you make accurate shots.
