Buying a suppressor — what to expect

Tax stamp: $0. The federal $200 suppressor tax was dropped on January 1, 2026.
Most states: since October 9, 2026, ATF is not enforcing Form 4 approval for suppressors. You fill out a Form 4473 and pass the NICS background check at pickup, the same as buying a handgun.
AK, CO, CT, GA, MI, MS, MT, NV, NC, ND, OH, OR, PA, WA, WI: state law still requires an approved ATF Form 4 before you take it home. We file the eForm 4 and take your prints and photo on our in-store Silencer Shop kiosk. ATF approval times vary.
Suppressors aren’t legal in every state, and these rules are changing quickly.

Canoe Creek Armory is a Class 07 FFL / Class 2 SOT. Questions before you order? Call (251) 368-4447.
