The utility model relates to fire arms. An appliance for decrease of sound level of small-arms comprises unit for junction with arm barrel, hollow body-shell connected to it by one end, with through axial channel and inlet cone with initial diameter that is equal to diameter of channel of barrel channel, transverse rings-partitions and end flange. For optimization of gas-dynamical parameters of silencer in inlet cone, coaxially to it, with gap, tapered nozzle is installed, in its outlet section coaxially, with gap, at least two placed in sequence broadening conical nozzles are installed. Gaps between the cone and the nozzles are connected to expansion chambers.
