Ownership Requirements
To own a suppressor in Missouri, you must meet federal requirements:
- Be 21 years or older to purchase from a dealer (a trustee on a trust can be 18 or older)
- Be a U.S. citizen or legal permanent resident
- Be legally allowed to possess firearms
- Complete ATF Form 4 with fingerprints and photograph
- Pass FBI background check
Missouri does not impose additional state requirements beyond federal law.
Hunting Regulations
Hunting with a suppressor is legal in Missouri. No Missouri statute and no state wildlife agency regulation restricts suppressor use while hunting.
Read that precisely. This is legality by the absence of a prohibition, not an express permission. Some states say in so many words that you may hunt with a suppressor. Missouri does not say anything at all. That is the ordinary situation and it is not cause for alarm, but it does mean an agency could add a rule without the legislature acting, so the current regulations guide is the thing to check, not this page.
Verify this yourself before you hunt
Hunting rules change by agency action as well as by legislature, and they can change between seasons. This reflects our reading of the sources cited above as of August 21, 2026. Before you take a suppressor into the field, read the current regulations guide from your state wildlife agency and confirm anything you are unsure about with them directly. Do not rely on this page, on a forum post, or on a dealer. The person holding the firearm is the person the warden talks to. This is general information, not legal advice.
State-Specific Notes
Missouri has no state-level restrictions on NFA items. The Second Amendment Preservation Act limits state cooperation with federal enforcement; it adds no rules of its own.

What State Law Actually Says
RSMo § 571.020.1(6)(c) makes it an offense to knowingly possess, manufacture, transport, repair or sell “[a]ny of the following in violation of federal law … (c) A firearm silencer.” A class D felony.
The federal condition is part of the offense element itself, so lawful NFA possession is simply not an offense. Note that the separate conformity defense at § 571.020.2 covers subdivisions (1) to (5) and does not reach subdivision (6). It does not need to.
Local Rules and Preemption
RSMo § 21.750.1 occupies “the entire field of legislation touching in any way firearms, components, ammunition and supplies.” Mo. Const. art. I, § 23, amended in 2014, extends to “ammunition, and accessories typical to the normal function of such arms” and applies strict scrutiny.
Worth Knowing
Missouri’s Second Amendment Preservation Act is unenforceable. The United States sued, and the Eighth Circuit affirmed the judgment striking it in 2024: “a State cannot invalidate federal law to itself.” The sections remain printed in the Revised Statutes but have no effect.
