How to Buy a Suppressor: A Plain-English Guide to How It Works Now

Getting a suppressor is simpler than it used to be. This guide explains how it works now, in plain words, and why your local dealer is still step one. You can see suppressor listings on Gun Search Engine while you read.

Per ATF guidance as of October 2026; rules may change. Check your state and local rules with your local dealer before you buy.

The chart at the top shows how suppressors compare with the other big categories listed on Gun Search Engine.

What a suppressor does and doesn't do

A suppressor, also called a silencer or a can, threads or clamps onto the muzzle and slows the hot gas leaving the barrel. That takes the edge off the sound of each shot and the blast you feel at the bench. It is easier on your hearing and on the people next to you.

It does not make a gun silent. A suppressed rifle is still loud, and most shooters still wear ear protection with one.

“A suppressor makes a gun quieter. It does not make it silent.”

What changed

For a long time, getting a suppressor meant a federal tax, a federal approval wait and a registration step before you could take it home. That has changed in three steps.

• The tax went to zero. Earlier this year, Congress cut the federal tax on suppressors to zero.
• A court ruled against the old paperwork. With the tax gone, a federal court ruled that the federal approval and registration rules could not be enforced for suppressors against the people in that case. The government chose not to appeal.
• ATF extended it to everyone. ATF then said it will stop enforcing the federal approval and registration steps for suppressors nationwide, not only for the people in the lawsuit.

Machine guns are a different story. They still carry the federal tax and the full federal process. The dates and the official documents are in the Sources list at the end of this post.

“The federal tax is gone and the federal approval wait is not being enforced. Your state's rules still apply.”

How it works at your local dealer

• Check your state first. Some states ban suppressors outright, and some only allow ones that are registered under federal law. Your dealer knows the rules where you live.
• Find a dealer who handles them. Not every gun shop carries suppressors. Browse suppressor listings to see which dealers do, then call ahead.
• Pick a can that fits your caliber. Every suppressor is rated for a largest caliber. You can shoot smaller rounds through it, never bigger. A rimfire can for .22 LR is a common first choice. Pistol cans are often built around 9mm, and rifle cans around 5.56 and up.
• Fill out the background check form. You complete the same federal form and instant background check you would for any gun from a dealer.
• Ask about registration. If your state still wants the item registered under federal law, your dealer can help you file a Form 4. Anyone can also choose to file one.

Makers like Dead Air and SilencerCo sell pistol, rifle and rimfire models. We don't endorse any one maker. Fit and use matter more than the logo. Slower, subsonic ammo is quieter through any can, which is why subsonic rifle rounds are popular with suppressor owners.

“Your state's rules come first. Your caliber comes second.”

Common questions

• Can I take it home the same day? Under the current federal guidance, a dealer can hand it over once your background check clears, the same as a gun. Your state may add its own steps, so ask your dealer.
• Can I get one in another state? With limited exceptions, a dealer can only sell a suppressor to someone who lives in the dealer's state. Expect to shop close to home.
• Do I still need a tax stamp? Not for a suppressor under the current federal guidance, because the federal tax is now zero. Machine guns still need one.
• What if the rules change back? They could. Right now ATF is choosing not to enforce parts of the law after a court ruling. That is a policy choice, not a new law, and other courts could see it differently. Some owners file a Form 4 anyway so they have the paperwork if things change.
• Is a suppressor legal everywhere? No. Some states ban them, and some limit where you can use one, including for hunting. Check before you buy.

The bottom line

Per ATF guidance as of October 2026; rules may change. The federal steps are much lighter than they used to be, but state and local law still decide what you can own and where you can use it. Your local dealer is your best source for what applies where you live.
