Identifying the Problem

Trigger Issues

Trigger problems can prevent a paintball gun from shooting. Check for debris or dirt around the trigger, and clean it with a cloth or paper towel. Make sure the trigger mechanism moves freely without obstruction. A worn or damaged trigger spring may need replacement for proper functionality.

Air Pressure Problems

Issues with compressed air can also affect your paintball gun’s performance. Inspect your tank’s pressure by looking at the gauge on the paintball marker. If it’s reading zero, there might be a lack of pressure in the tank or a leak in the CO2 line.

Paintball Jam

A jammed paintball can stop your gun from shooting. Carefully disassemble the barrel and remove any stuck paintballs. Clean the barrel with a squeegee or cloth to remove residue and ensure smooth passage for the paintballs.

Mechanical Failures

O-Ring leakage or re-cocking failure can cause mechanical issues in your paintball gun. Inspect the gun for leaks, especially below the barrel. If the O-Ring is defective, replace it and lubricate the new one. If the hammer isn’t applying enough pressure, increase the tension to resolve re-cocking failure.

Common Fixes

Cleaning and Lubricating

One of the primary fixes for a paintball gun that won’t shoot is cleaning and lubricating the internal components. Begin by disassembling the marker and removing dirt, debris, and paint residue using a soft cloth or squeegee. Properly lubricate the bolt and O-rings with a thin layer of recommended lubricant. Wiping off excess lubricant with a soft cloth ensures smooth operation.

Adjusting Trigger Settings

Adjusting the trigger settings can also help fix a paintball gun that won’t shoot. Check the trigger sensitivity and adjust it according to the manufacturer’s guidelines. Should the problem persist, inspect the trigger mechanism for any signs of wear or damage.

Checking Air Pressure

Low air pressure can be another cause of a paintball gun’s failure to shoot. Examine the air pressure in the tank; if it’s low, refill it. Additionally, check for leaks in the tank system or regulator by listening for hissing sounds.

Inspecting Seals and O-rings

Seals and O-rings are essential components in a paintball gun, ensuring proper air pressure regulation. Examine these components for any signs of damage or wear. If necessary, replace them to fix potential leaks.

Troubleshooting Specific Gun Models

Troubleshooting Specific Gun Models

Various paintball gun models come with their distinct challenges. In this section, we shall examine the common issues found in Mechanical and Electronic Markers and how to resolve them.

Mechanical Markers

Mechanical markers are more straightforward than electronic ones. If your mechanical marker isn’t shooting, follow these steps:

  • Clean the marker thoroughly using a cloth or paper towel to remove dirt and grime.
  • Properly lubricate the marker by applying a thin layer of the recommended lubricant to the bolt and O-rings.
  • Check and fix any re-cocking issues by increasing the tension on the hammer if required.

Electronic Markers

Electronic markers have more complex systems and their troubleshooting could be different. Here are some general steps to fix your electronic paintball gun:

  • Ensure the battery is fully charged or replace it if necessary.
  • Inspect the circuit board for any visible damage or loose connections.
  • Refer to the marker’s user manual for model-specific troubleshooting guides and solutions.

Remember, always consult your paintball gun’s user manual or contact the gun’s manufacturer for further assistance if required. Proper maintenance and care of your paintball gun will reduce the chances of facing shooting or performance issues.

Seeking Professional Help

While many paintball gun issues can be resolved through cleaning and maintenance, there are times when seeking professional help is necessary. If you’ve tried troubleshooting it yourself and the gun still won’t shoot, consider taking it to a specialist.

Paintball gun experts will have the experience and expertise to accurately diagnose and fix the problem. This not only saves time and effort but can also prevent further damage to the gun caused by incorrect repairs.

Locate a reputable paintball store or repair shop in your area by searching online or asking for recommendations from fellow paintball enthusiasts. Remember, it’s essential to choose a reliable professional to ensure your paintball gun functions well and lasts longer.

Proper Maintenance and Care

Proper Maintenance and Care

Proper maintenance and care are crucial in ensuring the smooth operation of your paintball gun. Regular cleaning and lubrication can help prevent issues and extend the life of your marker. Begin by inspecting the gun for any visible dirt, debris, or paint residue.

Clean the marker using a cloth or paper towel to wipe away any dirt and grime from its surface. If you have an air compressor, it can also be used to blow out dust and debris from the gun’s interior. Cleaning the barrel is equally important; use a barrel swab or squeegee to remove any obstructions or built-up paint.

Once clean, it’s essential to lubricate the internal components of the paintball gun. Using paintball-specific oil or grease, apply a thin layer to the moving parts, such as the hammer and bolt. This step helps to ensure smooth operation and reduces the likelihood of re-cocking failures or other mechanical issues.

Proper storage of your paintball gun is also vital. Store your marker in a cool, dry place, away from direct sunlight or extreme temperatures. Always remove air tanks and paintballs before storing the gun, and use a barrel sock or plug to prevent accidental firing.

Lastly, inspect your paintball gun regularly for any signs of wear or damage. If you notice any issues, address them promptly, either by troubleshooting the problem yourself or seeking assistance from a professional repair service.

Final thoughts on marker maintenance


If you’re struggling with a paintball gun that won’t shoot, you might have some questions. In this FAQ section, we will address a few common queries to help you get back on track.

What should I check first if my paintball gun won’t shoot?

Start by checking the air and CO2 ducts, as they might be blocked or damaged. If this doesn’t resolve the issue, inspect the gun for any worn or damaged parts, such as O-rings or the feeder spring, and replace them as necessary.

How can I clean and lubricate my paintball gun?

First, remove the air source by unthreading the ASA (Air Source Adaptor) from the gun. Next, disassemble the gun carefully and clean each part before applying suitable lubricant.

Can adjusting the velocity help fix a paintball gun that won’t shoot?

Yes, if your paintball gun is unable to re-cock due to low pressure, increasing the tension on the hammer can resolve the problem.

What should I do if my paintball gun is jamming?

Remove the air source, examine the gun for broken paintballs or debris, and clean it accordingly. You may also need to clear or adjust the paintball hopper to prevent further jamming issues.
