How to Make a Suppressor

Measure the diameter of the paintball gun's barrel. To do this, simply place one end of the measuring tape on the end of the barrel and measure straight up along the widest part of the circular barrel. This will give you the most accurate measurement of the diameter of the gun's barrel.

Measure the distance across the barrel. Use measuring tape or a ruler to measure the entire distance across the barrel. In other words, do not just measure the hole.

Purchase one piece of 1 inch (2.5 cm) PVC pipe, and one piece of 2 inch (5.1 cm) PVC pipe. The inches refer to the width/diameter of the pipe, not the length. These pipes will create the framework for the suppressor.

Cut the 2 inch PVC pipe to a length of 10 inches. You can cut the pipe using a handsaw, a hacksaw, a plastic pipe cutter, or a miter saw. Simply measure from one end of the pipe until you reach ten inches, mark the spot with a pencil, and then cut the pipe accordingly. Remember that if you measure twice, you'll only have to cut once.

Cut the 1 inch (2.5 cm) PVC pipe to a length of 12 inches (30.5 cm). Just measure out until you've found the 12-inch mark, and mark it with a pencil. This will be your suppressor's barrel. Note: These lengths may be adjusted for different size paintball guns. Longer suppressors are more unwieldy, but may increase dampening effect. The suppressor's barrel should always be 2 inches (5.1 cm) longer than the other PVC pipe, no matter which measurements you use.Make a Suppressor Step 4Bullet1.jpg

Draw a line of drill holes down the suppressor barrel. Using magic marker, draw a line of drill holes down the suppressor barrel, evenly spaced with ⁄4 inch (0.6 cm) between them. Use measuring tape to evenly measure the holes, and make sure to keep the line straight.

Draw another line of drill holes down the barrel. Now, turn the suppressor barrel 1/4, or 90 degrees, and draw another line. Use the same technique you used to mark the holes the last time.

Drill the holes with a ⁄16 inch (0.5 cm) drill-bit. Do not stop when you drill through the first surface. Drill through to the other side, so that you can see straight through. When you are finished, you should have four lines of parallel drill holes. You can use a hand drill, but a drill press is preferable. Use a drill-bit of size appropriate to the size of your projectiles. The holes should be smaller than the projectiles. Consult a permitted manufacturer to ensure that your drill-bit is the correct size.

Sand the inside and outside of the suppressor barrel, and the inside of the 2 inch (5.1 cm) PVC pipe. Use a rotary tool or sandpaper to smooth out any imperfections.

Create the end caps. If you have a jigsaw or scroll saw, you can make end caps from a piece of wood. If not, you can use thick cardboard or another sturdy material. Here is how you make the end caps: Trace a circle on the wood or cardboard around the 2 inch (5.1 cm) PVC pipe.Make a Suppressor Step 9Bullet1.jpg Within this circle, trace around the suppressor barrel, creating a donut shape.Make a Suppressor Step 9Bullet2.jpg Cut out the end caps. The end caps should fit securely around the barrel, and within the 2 inch (5.1 cm) PVC pipe.Make a Suppressor Step 9Bullet3.jpg

Slide the suppressor barrel into the larger pipe. The barrel should extend straight through the 2 inch (5.1 cm) PVC pipe to the other side.

Attach the end cap securely around the barrel of the suppressor, within the PVC pipe. It should snugly fit in place.

Secure the end cap with crazy glue or caulking. Give the glue time to dry before you touch the end cap again. The barrel should extend two inches out of the 2 inch (5.1 cm) PVC pipe, and the end cap should be on the other side.Make a Suppressor Step 11Bullet2.jpg

Stuff the space between barrel and 2 inch (5.1 cm) PVC pipe firmly with steel wool, cotton balls, heating insulation, or mattress foam. This will secure the two pieces of pipe, which are the two main parts of the suppressor, firmly in place.

Add the other end cap. Secure it with crazy glue or caulking.

Attach the barrel of the silencer to the barrel of your paintball gun. Neatly place the suppressor over the barrel of your paintball gun. This is why the suppressor has to be wider than the barrel of your gun, so that it can fit over it neatly.

Secure the barrel with a 1/2 inch (5.1 cm) to 2 inch (5.1 cm) hose clamp. Just use the clamp to secure the barrel in place, and use a screwdriver to turn the screw that keeps it in position. You're all done! Again, just remember that this is an illegal suppressor unless it has been properly registered.
