The Umarex K3 Neo suppressor is an exhaust device mounted on the end of the barrel, which effectively reduces the sound and recoil accompanying the firing.
The suppressor is made of lightweight, corrosion-resistant anodized aluminum. The silencer's 3-chamber design uses a baffle system and lightweight acoustic foam filling, resulting in a noticeable silencing of the shot. The device fits windcheaters with barrels ending in 1/2"-20 UNF male thread.
Note that the discharge device is intended only for air guns in 4.5 mm caliber.
