The Energetic Armament 5.56mm flash hiding end cap is a drop-in end cap made to cut flash signature on compatible silencers (Energetic Armament part no. EA38). Energetic Armament lists it for both the VOX and ARX series, so owners can change flash performance without replacing the whole can. It is machined in the USA from 17-4PH stainless steel and finished in black nitride. The cap has no provision for a wipe, which keeps the design aimed at flash reduction alone. It is an optional upgrade for 5.56mm shooters who want less muzzle flash.
