Specially designed for small calibers
SubSonic is a series of small, light and low-cost silencers made specifically for .17 and .22, respectively.
Standard SubSonic silencers are front-mounted and cover no part of the barrel.
Over-barrel versions are available as “SubSonic OB”, which cover about 12 cm of the barrel, has steel threads and a small internal muzzle brake. The SubSonic OB offers additional suppression of small calibers
