The Energetic Armament EA31 is a 5.56mm muzzle device built for shooters who want effective flash reduction without the complexity of a full suppressor. Threaded 1/2x28 to fit most modern AR-15s and 5.56 rifles, this nitride-finished brake works hard to tame muzzle flash under low-light conditions—a real advantage whether you're running night drills at the range, hunting in dim timber, or training with a carbine in variable light. At just 5.7 ounces, it won't throw off your rifle's balance, and the solid nitride coating stands up to hard use and corrosion.
The EA31 arrives with a 5.56 end cap included, so you're ready to thread it on out of the box. If your rifle wears a 1/2x28 muzzle (the standard on most 5.56 AR platforms), this is a straightforward swap. It's the kind of no-frills component that does one job well: cut flash and keep your sight picture cleaner when things happen fast or when ambient light is working against you.
Not a suppressor and not a compensator—the EA31 is a dedicated flash can for shooters who prioritize visibility and target acquisition over recoil management. Whether you're running a home-defense rifle, a competition carbine, or a hunting gun in early morning or late evening, this device earns its place on the muzzle.

Yes—the EA31 is threaded 1/2x28, which is the standard muzzle thread on virtually all modern AR-15s and 5.56 rifles. If your barrel is threaded 1/2x28, you're good to go.
The EA31 comes with a 5.56 end cap, so you have what you need for direct installation. You'll just need an armorers wrench or muzzle device tool to thread it on securely.
The EA31 is a flash reduction device, not a compensator or brake. At 5.7 ounces, it adds minimal weight and won't significantly change your rifle's recoil behavior—its job is to manage flash, not manage recoil.
Nitride is a proven hard-coat finish used on quality firearm components. It resists corrosion and holds up well to regular use and cleaning, making it suitable for duty, hunting, and range applications.
