how to make a silencer for a paintball markerWant to make a paintball silencer? With PVC pipe, a reducer, and some cotton balls, you can create a suppressor that will reduce the noise of your paintball marker.


  • PVC pipe
  • Reducer
  • Cotton balls


  1. Cut the PVC pipe to the desired length.
  2. Insert the reducer into one end of the PVC pipe.
  3. Stuff the cotton balls into the PVC pipe until it is full.
  4. Attach the paintball marker to the other end of the PVC pipe.
  5. Test the silencer by firing the paintball marker.

Key Takeaways

  • PVC pipe
  • Reducer
  • Cotton balls
  • Drill


To make a paintball silencer, you’ll need:

  • PVC slightly larger than your barrel.
  • PVC pipe 1 larger than your barrel.
  • 2 PVC reducers that fit the PVC.
  • A drill with a dremel bit.
  • A paintball marker.
  • Cotton balls.
  • Black plastic spray paint.
  • Sandpaper.
  • A hammer.
  • A PVC cutter.
  • A hacksaw.


Along with the materials, you’ll need the following tools to make a paintball silencer:

  • Drill: A drill will be used to create holes in the pipe for sound dispersion.
  • Dremel: A dremel tool is helpful for cutting out ridges and shaping the PVC pipes.
  • Hammer: You’ll need a hammer to knock down the reducer on the pipe.
  • Hacksaw/Sanding Paper: These tools are necessary for cutting and sanding down any rough edges on your silencer.

These tools are essential in creating your own DIY paintball silencer. The drill allows you to create holes in order to reduce sound when firing, while using a dremel can help shape and cut specific parts of your PVC pipes as needed.

The hammer comes into play when knocking down ridges or making adjustments, ensuring that everything fits together smoothly. Lastly, having a hacksaw or sandpaper handy ensures that any sharp edges are smoothed out before painting your homemade paintball silencer black.

Step 1: Cut Out Ridge

Step 1: Cut Out Ridge
Cut out the ridge that keeps the pipe from going deeper into the reducer.

This will allow the pipe to fit snugly inside the reducer.

Be careful not to cut too much, as you don’t want the pipe to be loose inside the reducer.

Step 2: Knock Reducer Down Pipe

Step 2: Knock Reducer Down Pipe
After cutting out the ridge, knock the reducer down the pipe until it’s flush with the end.

Use a hammer to tap the reducer down gently, being careful not to damage the pipe.

You may need to use a wrench to hold the pipe in place while you tap the reducer down.

Step 3: Cut Tube 1 From Reducer

Step 3: Cut Tube 1 From Reducer
Before moving on, you’ll need to cut the tube 1 from the reducer. Here’s how to do it:

  1. Use a hacksaw to carefully cut through the PVC pipe where it meets the reducer.
  2. Once you have made the initial cut, continue sawing until you completely remove tube 1 from the reducer.
  3. After removing tube 1, take some sandpaper and gently sand down any rough edges or burrs on both ends of the remaining pipe and inside of your newly created hole in that reducer.
  4. Make sure that your new hole is smooth enough for a snug fit when reassembled.

By following these steps, you can effectively remove tube 1 from your paintball silencer project while ensuring a clean and precise fit between all components of your homemade silencer assembly.

Step 4: Drill Holes in Pipe

Step 4: Drill Holes in Pipe
With the dremel bit, drill 5 holes evenly spaced around the pipe.

The holes should be 1/8 inch in diameter and 1/2 inch deep.

Hole Size Spacing Number Type of Drill Bit Depth
1/8 inch 1/2 inch 5 Dremel bit 1/2 inch

Step 5: Sand Inside of Pipe

Step 5: Sand Inside of Pipe

After drilling holes in the pipe, sand the inside of the pipe to smooth out any rough edges.

How to Sand a Pipe

  1. Use a piece of sandpaper that’s the same grit as the pipe.
  2. Hold the sandpaper against the inside of the pipe and move it in a circular motion.
  3. Continue sanding until the inside of the pipe is smooth.
  4. Wipe away any dust with a clean cloth.
  5. Repeat steps 2-4 until the inside of the pipe is smooth to your satisfaction.

Step 6: Cut Larger Pipe Shorter

Step 6: Cut Larger Pipe Shorter
Once you have sanded the inside of the pipe, it’s time to cut the larger pipe slightly shorter than the smaller pipe in the reducer.

Using a PVC cutter or hacksaw, carefully measure and mark where you need to make your cut on the larger pipe. Remember to take into account any additional length needed for attaching other components later on.

Once marked, securely hold onto one end of the larger pipe and begin cutting along your marked line with steady pressure until you reach all sides of it. Take caution not to rush this process as precision is key for optimal performance.

Step 7: Stuff Cotton Balls Between Pipes

Step 7: Stuff Cotton Balls Between Pipes
Stuff a few cotton balls between the pipes.

The cotton will help to absorb the sound of the paintball gun.

You can use as much or as little cotton as you want, but make sure that the cotton is dense enough to absorb the sound.

You can also use other materials instead of cotton, such as foam or felt.

Just make sure that the material is dense and will absorb the sound.

Step 8: Paint Silencer Black

Step 8: Paint Silencer Black
With the cotton balls in place, paint the silencer black.

Allow the paint to dry completely before using the silencer.
