Thunder Beast 338 Ultra Gen 2 Suppressor - Brake Attach

For those who push precision to the extreme, the Thunder Beast ULTRA 338 Gen2 BA Suppressor is a magnum-rated marvel built for pinpoint consistency and uncompromising suppression. Designed around big-bore favorites like .338 Lapua Magnum and .338 RUM, this Gen2 model delivers world-class sound performance in a lightweight, ultra-rugged profile made to thrive under hard use.

This variant features a flat-endcap design, prioritizing compact efficiency while offering a substantial 32% recoil reduction—ideal for long-range bolt guns, competitive platforms, and professional use. Built with 100% Grade 5 titanium and a tubeless fully welded baffle core, the ULTRA 338 BA ensures superior strength, heat resistance, and rock-solid point-of-impact repeatability. The Brake Attach (BA) mounting system offers seamless compatibility with TBAC’s legacy 338BA and 30BA muzzle brakes, making it a natural upgrade for existing Thunder Beast users.
