The DangerWerx M11 Threaded Barrel is a replacement outer barrel for the KWA Mac 11 GBB airsoft gun. This threaded barrel uses -14mm, or CCW threads, so it is compatible with most airsoft mock suppressors.
This silencer mount is not an adapter, but a complete replacement outer barrel. DangerWerx includes two o-rings for tension, keeping the barrel extension or mock suppressor tight and preventing gradual loosening.
The DangerWerx Mac 11 Threaded Barrel fits KWA NS2 M11A1 SMG airsoft guns, and will accommodate almost any -14mm airsoft silencer.
