Thunder Beast 338 Ultra Gen 2 Suppressor - Brake Attach - Reduced Recoil

The ULTRA 338 Gen2 RR-BA is Thunder Beast Arms Corp’s most advanced .338-caliber suppressor, purpose-built for long-range precision shooters who demand maximum suppression and enhanced recoil control. The RR (Race Ready) variant features a redesigned end cap that nearly doubles recoil reduction compared to the standard flat-cap model—offering up to 54% recoil reduction on .338 Lapua Magnum platforms.

Constructed from 100% titanium with a tubeless, fully welded baffle stack, the ULTRA 338 RR-BA delivers class-leading sound suppression, rock-solid point-of-impact repeatability, and lightweight handling. The BA (Brake Attach) mount is compatible with legacy 338BA and 30BA brakes, making it ideal for shooters already invested in the TBAC ecosystem.
