How to Fix a Nerf Gun Trigger?

If you’re an avid Nerf enthusiast, then you know how frustrating it can be when your favorite Nerf gun stops working. One of the most common issues that Nerf gun owners face is a malfunctioning trigger. Luckily, fixing a Nerf gun trigger is a simple and easy process that you can do on your own.

In this article, we will guide you through the steps you need to take to fix your Nerf trigger, and get your automatic Nerf gun up and running in no time.

Understanding the Nerf Gun Trigger Mechanism

Before we get started, it’s important to understand how the Nerf blaster trigger works. The trigger mechanism is responsible for releasing the plunger that sends the dart out of the gun. The trigger consists of a spring and a catch.

When you pull the trigger, it compresses the spring, which then releases the catch, and the plunger is pushed forward, sending the dart flying.

Diagnosing the Problem

The first step in fixing is to diagnose the problem. There are a few different things that could be causing your trigger to malfunction. The most common issues are a broken catch or a weak spring. To diagnose the problem, take apart your Nerf gun and examine the trigger mechanism.

Fixing a Broken Catch

If the catch is broken, you will need to replace it. You can purchase replacement catches online or at your local toy store. To replace the catch, remove the old catch from the trigger mechanism and insert the new one. Make sure that the new catch is properly aligned with the trigger and that it is securely in place.

Fixing a Weak Spring

If the spring is weak, you will need to replace it. You can purchase replacement springs online or at your local hardware store.

To replace the spring, remove the old spring from the trigger mechanism and insert the new one. Make sure that the new spring is the correct size and strength for your Nerf gun.

Lubricating the Trigger Mechanism

Sometimes, the trigger mechanism simply needs to be lubricated. Over time, the trigger and catch can become stiff, making it difficult to pull the trigger. To lubricate the trigger mechanism, use a small amount of silicone lubricant or WD-40.

Apply the lubricant to the trigger and catch, and then test the trigger to see if it moves smoothly.

Reassembling the Nerf Gun

Once you have fixed the trigger, it’s time to reassemble your Nerf gun. Make sure that all of the parts are properly aligned and securely in place. Test the trigger to make sure that it is working correctly before you load your Nerf gun and start firing.

Preventing Future Problems

To prevent future problems with your Nerf gun, it’s important to take proper care of your Nerf gun. Keep it clean and well-maintained, and avoid dropping or mishandling it.

If you notice any issues with your Nerf gun, such as a jammed dart or a malfunctioning trigger, address the problem immediately to prevent further damage.


Fixing a Nerf gun trigger is a simple process that you can do on your own with a few basic tools and replacement parts. By understanding how the trigger mechanism works and diagnosing the problem, you can easily fix your Nerf gun and get back to enjoying your favorite hobby.

Remember to take proper care of your Nerf blaster to prevent future problems, and always address any issues immediately.


No, it’s important to use a silicone lubricant or WD-40, as other types of lubricants may damage the trigger mechanism.

It’s recommended to have a few basic tools, such as a screwdriver, pliers, and lubricant, to fix a toy gun trigger. However, some simpler issues may not require any tools.
