There are a few different ways that you can make a bb gun suppressor. One common method is to use a length of PVC pipe. You’ll need to measure the diameter of your barrel and find a piece of PVC pipe that is slightly larger. Cut the pipe to the desired length and then drill a hole in the center. This will be your sound port. Next, wrap the outside of the pipe with some kind of foam or padding material. This will help to deaden the sound when the BBs travel through it. Finally, screw or tape the suppressor onto the end of your barrel and you’re ready to shoot!
Another popular method is to use an old soda bottle as your suppressor. Simply cut the bottom off of the bottle and then screw it onto the end of your barrel. You may need to experiment with different sizes and shapes of bottles to get the best results.
Either way, suppressors are relatively easy and inexpensive to make. With a little bit of creativity, you can come up with a design that works well for you and your gun.
