Various Silencers for your Airsoft Gun from brands such as M-etal, G&G, FMA, SRC, Pirate arms and 14mm thread CW or CCW.
A Silencer is generally a cosmetic addition to your airsoft gun but because most silencers have a foam filling, they also have a light damping effect. Very much quieter your gun will not be since most sound (in case of an AEG) comes from the gearbox.
