      This paper describes the designs and manufacturing and testing features of small-size silencers developed at the Institute of Technical Mechanics of the National Academy of Sciences of Ukraine and the State Space
      Agency of Ukraine for arms used in enclosed space.
      The topicality of the development is due to the use of stub-barreled arms by Ukrainian special subunits. With consideration for the features of existing silencers for submachine guns of special subunits, a line of compact silencer development was chosen. The paper formulates requirements for the design of silencers for stub-barreled small arms and material and manufacturing accuracy requirements for their components.
      The use of silent stub-barreled small arms in enclosed space without damaging the shooter’s organs of hearing is justified. In combat operations, sound suppression allows subunits to contact with one another and their commanders to have the situation under control.
      The paper shows the features of design solutions and describes the design of the silencers’ internal components and their effect on the operating efficiency for different embodiments of theirs.
      The paper presents the appearances, construction arrangements, and specifications of the small-size silencers developed and the results of their full-scale tests.
      The sound suppression efficiency of the silencers developed was measured with a sound level meter and verified by comparison tests with basic prototypes developed earlier. The efficiency proved to be (28 – 34) dBA, which is on a level with their best foreign counterparts. The test showed that:
      - the silencers do not affect firearm automatics and sustain standard firing regimes,
      - the silencers do not affect the shot grouping characteristics, and
      - the silencers do not affect other performance characteristics either.
      Hence the compact silencers developed for stub-barreled submachine guns (assault rifles) are efficient and reliable.
