The Energetic Armament VOX K2 7.62mm suppressor (Energetic Armament part no. EA11) is a compact .30 caliber can with a laser-welded, nitrided C300 maraging superalloy core. It stands 4.9 inches long and weighs 10.4 ounces, built for hard use where a short, light, high-temperature can is needed. The standard wipe end cap lets you run it with or without the wipe, and it takes optional flash hider end caps. A 5/8×24 direct thread adapter ships with it, and the 1.375×24 HUB pattern accepts industry-standard mounts. It suits a hunting rifle, a precision bolt gun or a .30 caliber gas gun.
