The Energetic Armament Ferox is a 12.5-ounce 5.56 and 6mm suppressor built for short and mid-length barrels, where back pressure and flash matter most. The core is 17-4 stainless heat treated to H900 and uses radial gas-bleed chambers instead of plain cones, which lowers back pressure without giving up sound reduction, and the removable end cap has flash-hider tines as standard. This is the Magpul FDE Cerakote over black nitride version.
Rated for 5.56 NATO, 223, 5.45x39 and 5.7x28 on full auto, plus 224 Valkyrie and 6mm ARC, with no barrel length restrictions under 1,000 F. It ships with a removable 1/2x28 direct-thread adapter and takes any 1.375x24 HUB or Bravo quick-detach mount. Every Energetic centerfire can carries the patented Serial ID Ring: the serial number lives on a separate ring, so if the core is ever damaged, Energetic replaces the core and your ring, your serial and your tax stamp stay the same. No new Form 4, no new wait. Lifetime guarantee, made in the USA.
