Classic Army's Replica up of the SOCOM silencer is top notch. The standard version for AEG's comes with 14mm anti-clockwise threat and will fit most Classic Army, ICS, Tokyo Marui and other common AEG's without the use of a thread adapter.  The alternate "clockwise" version is for custom AEG applications like the Systema PTW and other rare AEG's that only have options for 14mm+ thread.

Note: Airsoft silencers are used for cosmetic use only and offer no actual reduction in sound heard from an airsoft gun.
