The concentrator is designed for tracer bullets for hunting and sports firing. It has improved design which facilitates and simultaneously releases the tracer element from its seat allowing it to fly in the group of the shot cluster and accurately determine the hit. The necessary damping effect is also ensured as a result of which the concentrator can move along an axis coinciding with the axis of the barrel of the weapon. The concentrator consists of a monolith body including lower (1) and upper (6) lateral platform between which a cylindrical stem (4) is fitted. There are reinforcement ribs (5) along the external surface of the concentrator which are symmetrically inclined towards its axis. A seat (9) is fabricated in the upper lateral platform (6) the upper part of which has the form of a truncated cone, and the lower cylindrical part has a height equal or bigger than that of the truncated cone. A fixing ring (11) consisting of elastic plates (12) is machined in the zone of the transmission between the truncated cone and the cylindrical part of the seat (9).
