Efficiency optimization is at the core of the Energetic Armament engineering ethos: Delivering the most dB reduction per ounce of weight and linear inch of silencer. Utilizing 17-4 Stainless Steel heat treated to the H900 condition, the Ferox is engineered to be ultra-strong without sacrificing durability. Developed specifically for 5.56mm platforms; particularly for short and mid barrel lengths optimizing low back pressure and excellent sound suppression.

Weighing only 12.5oz, the precision engineered radial gas bleed off chambers allows for lower backpressure vs conventional baffle design without sacrificing sound reduction performance.  A lightweight design and increased internal volume while maintaining a small outer envelope equals better sound attenuation. Thinner walls also mean better heat transfer as the silencer converts the kinetic energy of high- speed muzzle gasses into heat rather than sound. All these factors produce an optimized geometry to give you the best possible performance for the most compact, light silencer possible. Efficiency is engineered into every Energetic Armament design and the Ferox continues that legacy.

The Ferox ships with a removable 1/2-28 direct thread adapter and is compatible with all industry standard 1.375×24 HUB or Bravo style quick-disconnect mounting systems.

Flash signature mitigation, critical on 5.56mm platforms, was engineered into the design from the very start. The flash hider end cap of the Ferox is removable and features functional flash reducing tines as standard equipment. The Ferox is quiet… really quiet… with low, even tone that gives your firearms the sound you want. Less gas to the face and less sound to the shooter’s ears; the way it should be!

The Ferox is a robust, well-engineered design, tested and proven. Backed by the best customer service in the industry and guaranteed with the patented Energetic Armament serial ID ring. Buying an EA silencer is becoming part of our family of shooters.
