Umarex Umarex Silencer SD4 14 mm CCW

The Umarex long gun silencer SD4 14 mm is the ideal choice for air guns in calibers up to 6.35 mm (.25). Due to its 6-chamber design and the precisely CNC-machined aluminum housing, the silencer achieves outstanding sound insulation and reduces noise by 25 dB, especially at higher energies. But even with air guns in calibers 4.5 mm (.177) and 5.5 mm (.22), the SD4 provides noticeable sound dampening. Thanks to its versatile compatibility, the silencer is delivered with two thread adapters (14 mm left and ½“-20 UNF), making it suitable for a wide range of weapons.
