Energetic Armament EA31 SOB 5.56mm 1/2x28 Nitride Muzzle Device

The Energetic Armament EA31 is a compact SOB flash can-style muzzle device built around a standard 1/2x28 thread pitch for direct-thread mounting on 5.56mm AR-15 pattern barrels chambered in 5.56 NATO or .223 Remington.

Treated with a rugged black nitride finish, the EA31 resists wear and corrosion under hard use in the field or on the range. At an overall length of 3.47", it adds minimal bulk to the host rifle while helping to tame blast and reduce flash signature at the muzzle.

The muzzle device ships with a 1/2x28 direct thread adapter and a dedicated 5.56mm end cap, giving you everything needed for straightforward installation on a standard barrel. Whether you are building a new rifle or upgrading an existing setup, the EA31 offers a simple, durable solution for directing muzzle blast.
