Like all Seekins Precision products, the Nest Flash Hider far surpasses standard products. The unique design swirls hot gases immediately as they exit the muzzle, extinguishing the flame to eliminate the visible flash. Built for hard use, the Nest Flash Hider is precision machined from steel and melonite coated to increase durability. Melonite makes cleaning easy because carbon fouling does not adhere to it as well as it does on other finishes. The design is engineered to eliminate the annoying "ping" often associated with this configuration.The non-symmetrical design does not need to be timed, making installation simple and hassle free, no crush or peel washers are necessary. No special tools are required. Flats machined at the rear of the Nest Flash Hider will accommodate a number of wrench styles that are readily available.
