The revolutionary 50 BMG Suppressor

Being long-range oriented, a 50 BMG suppressor was always on the horizon for Thunder Beast. The goal statement for the R&D of this was very simple: Make a 50 suppressor so you can shoot 50BMG all day recoil-wise, with only normal earplugs.

The result will be shocking to anyone who has shot a lot of 50BMG with a muzzle brake or normal suppressor. The ULTRA50 reduces recoil by 65% compared to a bare muzzle while presenting a peak dBA sound pressure level at the shooter's ear of approximately 136 dB. For comparison's sake, the next most well known "braked 50 suppressor" is 20 -- twenty -- dB louder at the shooter's ear.

The ULTRA50 is modular in that it has a center section that, when removed, makes the overall length about 4.0" shorter.

The ULTRA50 is available only in the Big-SR or "BSR" mount. As the name suggests, this a scaled-up version of Thunder Beast's SR "Secondary Retention" system and will mount to one of their BSR-NTB muzzle devices.
