Q&A for How to Make a Suppressor

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.

With this design it is recommended, but other designs may require something different, it mainly depends on weight. Just be sure that it's secured enough so that the suppressor is centered, otherwise you'll have terrible accuracy.

You would need to consult your local laws as the answer could depend on your state, city, etc.

It should, but you would have to modify it slightly. Make the spacers at 2-inch intervals between the steel wool.

Slide would not interfere, because there will be a metal clamp held together by a screw. The clamp will hold the inner pipe to the barrel without being permanent. The tighter the screw is, the tighter the hold is to the barrel.

It would. Bear in mind the notes as to response and sonic barrier, however. If your projectile exits at supersonic speed, at sea level, in dry air, you would still hear the sonic 'crack.'

The distance can vary. Generally, you want to have it on far enough that it will remain centered. So, 1 inch will do just fine, but adding extra inches won't hurt. (A lightweight suppressor doesn't need as much attachment as a heavyweight suppressor).

You can purchase them a sporting goods store or online. Most also require co2 or high pressure air.

Unfortunately, a homemade suppressor like this one won't work very well. The way a suppressor works is by deducting from the response of the gun. (A gun makes two sounds: the response, which is the gunpowder igniting, and the bullet breaking the sonic barrier. A paintball gun only has a response). Since this is just PVC pipe, it lacks the necessary components to silence any form of projectile.

Follow the instructions listed in the article above.

This is made for use with a paintball gun, not for use with a real rifle. It is illegal to use this with a real rifle in most places without proper certifications and/or tax stamps.

The holes, theoretically, are supposed to act as baffles which distribute the air/shockwave and dampen the sound, since there is not as much force exiting the end of the barrel. This is the reason why suppressors reduce the weapon's damage.
