How to Fix a Paintball Gun That Won’t Shoot?


If your paintball gun doesn’t shoot anymore, it may be time to take action. Simple cleaning will help prevent future problems from occurring. However, more serious issues may require a professional. For example, a paintball gun may have a faulty detent or be prone to double firing. To check this, hold the gun vertically down and check if any balls fall out. If you see that this is the case, you should consider replacing the ball detent.
If you want to know how to fix a paintball gun that won’t shoot, there are a couple of things that you can try before calling a service shop. First, you can check to see if there is too much paint buildup inside the gun. If so, you’ll need to wipe it down with a dry towel.
Many paintball guns are prone to malfunctions. However, with a little bit of effort, you can easily repair most of them. Whether you are using a standard blow-style paintball gun or a custom-made one, you can find a solution. If you are not handy, you can try to find a guide online or in a paintball forum. Usually, the problem is caused by a damaged O-ring around the ASA fitting.

Check the Air Source

One of the most common reasons why a paintball gun won’t shoot is a leaky air tank. If this is the case, you should replace it. Another possible reason is a blocked barrel. Usually, a leak in the air tank can be fixed with some cleaning or adjustments, but some paintball guns will require the replacement of worn parts. Before performing maintenance, it is a good idea to check the owner’s manual.
A leaky air tank can be a serious problem. Besides the obvious safety issue, a leaky air tank can lead to an explosion. If it’s too tight, the gas could leak out and cause an explosion.
Check the Tank O-rings
If you’re experiencing problems shooting your paintball gun, it might be time to check the Tank O-rings. These o-rings seal the tank valve when you put the tank on the gun. Polyurethane o-rings are the most common, but you can also use PTFE o-rings, which are white and have a higher durometer. However, they may not seal as well as polyurethane o-rings. In either case, you’ll want to avoid removing the O-rings, as donkey threads can damage them.
Check the Hoses and Fittings
Another cause is that the gun is not aligning properly. Sometimes, a paintball gun’s solenoid head or rear banjo may not be aligned properly. In this case, you should check your rear 4-mm Microline hose. If this doesn’t work, you should replace the solenoid head.
Another common problem with a paintball gun is that it won’t recock. A lack of pressure on the hammer can cause a failure to recock the gun. You can increase the tension in the hammer by changing the hammer spring. Some paintball guns also have a built-in adjustment on the side of the hammer.
Check the Paintballs
A common cause of a paintball gun not shooting is a broken paintball. The paintball may not have been loaded properly, or it may not be the right size. If this is the case, you need to check the paintballs in the gun and clean it out regularly. You can also clean out the chamber with a squeegee if the paintballs get stuck in there.
Check for a Paintball Jam

If you’re having trouble shooting paintballs, the first thing to check for is a paintball jam. This can be caused by a paintball breaking inside the paintball gun’s barrel. To determine whether this is the case, remove the hopper or tank and inspect the barrel. If the paintball breaks farther down the barrel, it’s likely that there’s paint goop or gunk running down the barrel. If paintballs are spilling onto the bolt, this is also a sign that paintballs are breaking inside the barrel.
Clean the Barrel
If the barrel of your paintball gun is clogged with paint, it may not shoot correctly. This could be caused by a blocked hopper, bad paint, or even a barrel bore size that is too tight. In either case, cleaning and adjusting can solve the problem. In some cases, however, replacing worn parts is necessary. In this case, you should consult your gun manual first.
Clean the Paintball Hopper
A broken paintball will jam the barrel and cause the gun to stop firing. First, check the hopper to make sure that it’s free of dirt and moisture. If the paintball is wet, you may want to clean the hopper with a tissue and a new paintball.
Check for a Leak in the System
A paintball gun that isn’t shooting could be the result of a leak in the system. The seal around the barrel may be damaged, which allows gas to escape. When this happens, there is a risk of an explosion. Also, clogs or corrosion may weaken the seal.
