UMAREX SD5 Pistol Silencer – Dual-Thread Airgun & Airsoft Moderator
The UMAREX SD5 Silencer is a sleek, compact suppressor built for air pistols, CO₂ revolvers, and smaller carbine-style airguns. Featuring a 4-chamber internal design and a lightweight CNC-machined aluminium body, it delivers effective sound suppression—reducing muzzle report by up to 20 dB on airguns in .177 and .22 calibre.
Compact and understated, the SD5 brings both performance and aesthetics to your setup. Whether you’re looking to keep things quiet at the range or want a tidy accessory that completes your pistol build, this moderator fits the bill.
Includes Two Thread Adapters for Broad Compatibility:
½″-20 UNF (standard for most air pistols and carbines)
14mm CCW (left-hand) (suitable for many airsoft pistols)
