Sound-reducing mock suppressor that fits any airsoft gun with a 14mm CCW (Counter Clockwise) thread. Airsoft guns produce a moderate level of decibel, however, mock suppressors can really make a difference on the field. Thanks to the acoustic foam and lightweight construction, this mock suppressor will effectively absorb noise and echoes without affecting the balance of your gun. Thread: 14mm CCW Diameter: 40mm Length: 220mm To comply with local laws we will send the hollow mock suppressor and the second one with the foam discs to some countries. You need to check your local law if it's allowed to install the foam discs into the tube. We will also send you an installation guide.
