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.
Knights Armament
Overview
The KAC Suppressor 7.62 CRS in Flat Dark Earth (FDE) is designed for firearms chambered in 7.62x51 NATO. This suppressor effectively reduces the sound signature of your rifle, enhancing stealth and reducing recoil while maintaining accuracy. While it is primarily suited for heavier caliber builds, it can also be found in configurations that utilize a 5.56 NATO caliber, making it versatile for various shooting applications.
