Manufacturer claim
- Full-auto rated and described as built for high-volume fire. Caliber range is .17 to 5.56, including .243 / 6mm.
- Echo Zulu Defense reports 32+ dB of sound reduction.
- A hybrid design that the company says optimizes gas flow to cut backpressure, giving smoother cycling, less gas blowback and better recoil control on both gas-operated and bolt-action rifles.
- Built from Inconel 718 by Direct Metal Laser Sintering, which Echo Zulu Defense says gives superior strength and heat resistance while holding weight to 11.6 ounces. Finished in black High-Temp Cerakote suited to high-heat use.
