Suppressors, commonly referred to as "silencers," are devices fixed to the end of a firearm intended to muffle the sound of a shot being fired, not silence it.[1] They are also used on paintball guns, and can make it more difficult for opposing players to identify your position. There are many different ways to make a paintball gun suppressor, many of which employ common household and hardware materials.

Note: It is illegal to build a silencer for anything that fires a projectile without a $200 tax stamp on a Form 1 under the National Firearms Act, unless you are a licensed Class 3 Firearms dealer. This article is for demonstration purposes only! Some counties/municipalities, states, and countries ban silencers altogether, and because many paintball gun suppressors can be used for firearms as well, they too may be illegal in your area. Check your municipality's, state's, and country's laws on this matter before proceeding.[2]

1 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.
2 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.
3 Purchase one piece of 1 inch (2.5 cm) PVC pipe, and one piece of 2 inch (5.1 cm) PVC pipe.[3] The inches refer to the width/diameter of the pipe, not the length. These pipes will create the framework for the suppressor.
4 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.
5 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.
6 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 1⁄4 inch (0.6 cm) between them. Use measuring tape to evenly measure the holes, and make sure to keep the line straight.
7 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.
8 Drill the holes with a 3⁄16 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.[4] Consult a permitted manufacturer to ensure that your drill-bit is the correct size.
9 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.
10 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.
- Within this circle, trace around the suppressor barrel, creating a donut shape.
- Cut out the end caps. The end caps should fit securely around the barrel, and within the 2 inch (5.1 cm) PVC pipe.
11 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.
12 Attach the end cap securely around the barrel of the suppressor, within the PVC pipe. It should snugly fit in place.
13 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.
14 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.
15 Add the other end cap. Secure it with crazy glue or caulking.
16 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.
17 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.

Question How do I measure a gun barrel? Scott Thompson Firearms Instructor Scott Thompson is a Firearms Instructor based in Stapleton, Alabama. He is the Owner and Lead Instructor at Gulf Firearms Instruction, a Premier Firearms Training Academy that has been teaching citizens and law enforcement personnel for more than 31 years.

Before instructing at Gulf Firearms, he was a Police Officer for 25 years, and he is a Retired SWAT Officer. Scott Thompson Firearms Instructor Expert Answer To measure the length of a gun barrel, you typically insert an empty cartridge into the barrel's chamber and close the action. Then, using a cleaning rod, carefully insert it into the barrel until it reaches the end (muzzle). Measure the distance from the muzzle to the point where the cartridge is seated. This measurement provides the length of the gun barrel. Thanks! We're glad this was helpful. Thank you for your feedback.

In the US, air-powered guns (i.e., paintball guns, bb guns, pellet guns, air rifles, etc.) can be suppressed without paperwork so long as the suppressor cannot be removed from the barrel. If you welded on metal pipe, used PVC, or otherwise made it unremovable, you can add a suppressor legally without filing paperwork.
The BATF has decided that if a suppressor for an air gun can be easily removed, it is considered a firearm silencer and governed by firearm rules.

Warnings

Make sure that your paintball arena allows homemade suppressors. Thanks Helpful 67 Not Helpful 46
Never point a paintball gun, or any other weapon used to fire projectiles, at a person, pet or flammable or breakable object, except in appropriate paintball events. Thanks Helpful 38 Not Helpful 106
Under ATF law It is illegal to build a silencer for anything that fires a projectile without a permit. Some states ban silencers altogether, and because many paintball gun silencers can be used for firearms as well, they too may be illegal in your area. Check your state's laws on this matter before proceeding.[6] Thanks Helpful 2 Not Helpful 2
