đ¨ Update â October 9, 2026: ATF has issued a new non-enforcement policy covering suppressors, SBRs, SBSs, AND AOWs for everyone â not just customers in Free States. ATF is not enforcing NFA approval, registration, or tax-stamp requirements for these four item types; registration remains voluntary. The section below on SBRs/SBSs reflects the earlier, narrower ruling and no longer applies â ATF's new policy now includes SBRs and SBSs too. This is a non-enforcement policy, not a change in the law, and state law is unaffected.
As of January 1, 2026, the tax stamp fee is $0 for suppressors, SBRs, SBSs, and AOWs â Silencer Shop includes it automatically with every eligible purchase.
Free State Customers â Suppressors and AOWs
As of August 13, 2026, if you are in a free state and purchase a suppressor or AOW that originated from Silencer Shop, the registration requirement is also gone. No Form 4, no wait. Just complete a 4473 and pass a NICS background check at your dealer â the same as buying a rifle or handgun. The $0 tax stamp is still applied automatically at checkout, but no Form 4 is filed.
NFA State Customers and SBRs/SBSs â Form 4 Still Required
If you are in an NFA state (AK, CO, CT, GA, MI, MS, MT, NV, NC, ND, OH, OR, PA, WA, WI), state law still requires a Form 4 for suppressors and AOWs. The $0 stamp is included and the standard transfer process applies.

âSBRs and SBSs previously required a Form 4 in all states. As of October 9, 2026, ATF is no longer enforcing this requirement either â see the update banner above.
