The arrangement for extending and making the dispersal of the shot fired from shotguns more uniform especially for clay pigeon shooting ensures also that the shot is spread at relatively short distance from the gun muzzle. On the barrel muzzle a short tube with flared end with internal grooves is fitted, by menas of an adapter. The bottoms of the grooves in the choke part of the short tube form an extension of the cylindrical section of the nonchoked part of the barrel (3). The grooves continue also into the flared part of the short tube. The grooves are inclined at a small angle to the barrel bore centre line. This arrangement also prevents deformation of peripheral shot and this shot is stabilised.
