Product Description

Update, October 9, 2026: ATF no longer requires a Form 4, tax stamp, fingerprints or registration for suppressors, short-barreled rifles, short-barreled shotguns or AOWs. They now transfer on a standard Form 4473 with a background check. Anything below that mentions a Form 4, a wait or a tax stamp was written before this change. What changed

The B&T Stille 300 .30 caliber suppressor delivers professional-grade sound reduction for shooters who demand reliability and performance. This suppressor is built for hearing-safe hunting, range sessions, and home defense applications where noise control matters.

Additionally, the Stille 300 features a direct thread mount for secure, repeatable attachment. The 8.5″ barrel length balances sound suppression with handling, making it practical for rifles where shorter platforms aren’t an option. Moreover, titanium and Inconel construction ensure durability under sustained use.

Design and Construction

B&T engineered the Stille 300 with premium materials to withstand high-pressure .30 caliber rounds. The anodized black finish resists corrosion and provides a professional appearance. Additionally, HUB-compatible design opens compatibility pathways for shooters with existing mounting ecosystems.

What’s Included

Your purchase includes a 5/8X24 direct thread adapter for immediate installation on compatible barrels. This adapter eliminates the need for separate purchases and gets you to the range faster. Furthermore, the complete package simplifies the setup process for first-time suppressor users.

Ideal Use Cases

Hunters appreciate the Stille 300 for hearing-safe shooting without sacrificing point-of-aim accuracy. Range shooters benefit from reduced report and recoil management during long shooting sessions. Therefore, whether you’re pursuing game or honing marksmanship, this suppressor delivers in practical, everyday scenarios.

Buying a suppressor now: a Form 4473 and a background check. No Form 4.

Since October 9, 2026, ATF no longer requires a Form 4, tax stamp, fingerprints, photos or registration to buy a suppressor. It transfers like any other firearm: you fill out a Form 4473, pass a NICS background check, and it is yours. No months-long wait.

  • Texas buyers: suppressors are legal under Texas law. Western Sport has been an SOT / Class III dealer since 2007.
  • Outside Texas: we ship to an SOT dealer in your state, who completes the 4473 with you. Your state’s law still decides — some states ban suppressors, and some only allow ones registered with ATF.
  • Want it registered anyway? ATF still accepts a voluntary Form 4. Ask us.
