Plan your Class 3 dealer
Suppressors go through a Class 3 (SOT) dealer. The federal tax is $0, and ATF stopped enforcing the Form 4 wait on October 9, 2026, but some states still require federal registration. You still pay the dealer's transfer fee.

Price and stock
The CGS HELIOS 556MM SUPPRESSOR was hard to find in September 2026, in stock on only 4 of the 9 days we checked, and today none of the 2 retailers we track has it in stock right now. Prices barely moved in September 2026, holding around $1,050, so there haven't been real sales lately. Listed prices start at $899 at KY Gun Company for when it comes back.
