It is the belief of many that it is illegal to own or make a gun silencer in the U.S. However, the truth is that it is one hundred percent legal as long as the person making it completes the required paperwork and registration with the Bureau of Alcohol, Tobacco and Firearms, either online or over the phone. With that said, here is how to make your own gun silencer.
First, take the heat and pressure dispersement rod and drill holes into the sides of it. The holes should be about the size of the gun's standard ammunition. The middle of this rod needs to be just a little bigger than the bullets so that the bullets can pass through.
Next, glue a wooden washer to both ends of the rod. Be sure not to block the hole in the center. Then wrap aluminum screening around the rod and fit it tightly into a rubber cylinder. Pound the rod in if necessary; the rod should fit tightly enough that inserting it into the cylinder is difficult. Be sure to get the rod even with the bottom of the cylinder. The cylinder needs to be about an inch longer then the rod.
Then, insert a steel washer plug into the cylinder behind your displacement rod. This acts as a seal between your silencer and adapter. Insert the adapter and then the stabilizer washer plates into the tube. Then, drill tiny holes into the sides of the cylinder and insert screws to hold everything in place.
Next, with the use of a hammer, drive the rubber cylinder into a piece of PVC pipe. Make sure that the PVC pipe is double the length of the rubber cylinder. The adapter should be even with one end of the pipe and there should be a lot of empty space at the other end.
Now fill the empty end of the pipe with wooden and rubber washer plates, alternating each. Be sure to insert a separating disk after every four or six washers. All of the washers should fit into the pipe tightly and the hole in all of them should be just a little larger than the bullets.
Finally, insert a steel washer plug into the front of the PVC pipe. This completes your silencer.
With these easy step-by-step instructions, you should have no problem making your own gun silencer. Remember to file the proper paperwork with the ATF.
