Thunder Beast: Magnus-S-CB, .30 Cal Suppressor

Each Thunder Beast MAGNUS-S CB Suppressor will come with one 5/8x24 Muzzle Brake.

The MAGNUS is the quietest .30 cal suppressor on the market for almost every caliber -- .223's, 6mm's, 6.5mm's, 7mm's, and .30's -- up to .300 Norma Magnum. The only thing quieter -- in some cases -- is a 338 ULTRA GEN2, which is larger.

Best-for: Long-range shooting, Hunting, PRS

The Magnus-S (normal endcap version) is the shorter version of the Magnus and gives up little suppression while being over 2" shorter. Supression is between an Ultra 7 (Gen2) or Dominus-CB and the Ultra 9 (Gen2).
