A combination of steel and Aluminium gives us one heck of a sturdy all-metal QD silencer. With no tools required and only moment to add / remove your silencer, it combines easy use with looking cool. Although suppressors do not offer much difference with the sound in Airsoft generally, at least in gas weapons it will pull the source of the report and gas emission further away from your face. The tubular structure, although not quieting, will at least change the sound and possibly the some spread of the sound from your gas weapon. Combine that with VFC build quality, you have yourself one very neat suppressor. Even if your not that keen on markings yourself, they do look good in photos, in display cabinets and of course for close up / high res shots during photo-shoots, filming and other theatrical purposes.
