Shop Suppressors
A suppressor (often called a "silencer") is a device attached to or part of a firearm that reduces the noise and muzzle flash generated when firing. They do not make gunshots silent but lower the sound to safer decibel levels.
In the United States, suppressors are regulated by the National Firearms Act (NFA). They are legal in most states, but a few prohibit them entirely. You must also comply with all federal and local requirements before purchasing.
  • Be at least 21 years old (if purchasing through a dealer)
  • Live in a state where suppressor ownership is legal
  • Purchase from a licensed dealer (SOT Class 3)
  • Submit ATF Form 4 with a $200 tax stamp and pass a background check
Approval times vary, typically from 1-4 weeks. This depends on ATF backlogs, accuracy of paperwork, and overall application volume.
The "tax stamp" is the $200 fee required under the NFA for each suppressor (or other NFA item). Once approved, you'll receive a physical or digital stamp showing payment.
Individual: The suppressor is registered to you personally. Others may use the suppressor, but the owner must be present.
Trust/Corporation: Registered to a legal entity; multiple trustees/officers can have possession. Each responsible person must submit fingerprints and photos.
  • Advantages of individual filing
    • No additional paperwork or fees required
    • Are able to add it to a trust at a later date if so chose.
  • Disdvantages of individual filing
    • Others are not able to use the item without your being present.
  • Advantages of trust filing
    • Other trustees are able to use the item without need for any one individual to be present.
    • Estate and asset management.
  • Disadvantages of trust filing
    • All trustees are required to fill out an RPQ and be approved for possession. Should any one person be disapproved, the entire submission is disapproved and the process has to start all over again.
    • Organizing all members of a trust to be available to submit paperwork can be difficult.
    • Creating a trust can vary in cost from $50 to $600 depending on the complexity and how/who creates it.
You typically work with your SOT Class 3 dealer to complete the paperwork. You'll need personal information, fingerprints, photos, and, if using a trust, copies of trust documents with responsible persons' details. Always verify you're using the most current form.
In-Store: You can see it firsthand and get help with paperwork on-site.
Online: You buy from a website, then transfer to a local Class 3 dealer for paperwork and final delivery after approval.
You can legally use it in any location where firearm use is permitted in your state. Always follow all federal, state, and local regulations. Suppressors can be transported across state lines without extra paperwork, however, we recommend you keep a copy of approved paperwork with you when traveling/using NFA item. SBRs, SBSs, MGs, AOWs, DD's require an approved Form 20 to cross state lines.
Follow the manufacturer's guidelines for cleaning and maintenance. Some suppressors require periodic disassembly. Store it in a dry, secure location.
Generally, no. A CCW does not bypass federal NFA requirements. You must still submit the ATF Form 4, tax stamp, and pass the background check. A CCW might expedite some state processes, but not the federal ones.
If suppressors are legal in your new state, you typically do not need additional federal paperwork to move it (unlike some other NFA items). Always verify the new state's laws before moving.
If you own it individually, only you (the registered owner) can possess it/others cannot borrow it without you being present. However, others may use the suppressor while you are present. If it's owned by a trust or corporation, any trustee/authorized officer may possess it.
Possessing or manufacturing a suppressor without proper approval can lead to heavy fines and imprisonment. Always follow all applicable laws and regulations.
