The Spectre™ 22 has the quietest first round “pop” of any rimfire silencer and is made of durable stainless steel construction, which enables it to handle a range of ammunition from .22LR to 5.7mm. SilencerCo’s unique CTA™ (Click Together Assembly) baffle design makes the Spectre 22 equipped to handle the harshness and debris of rimfire ammunition with ease. After heavy use – even full auto .22LR – the Spectre 22 will remain exceptionally quiet, reliable, and user-serviceable.
