SUBSTANCE: the small arms has a frame and a barrel and a magazine with a two-row arrangement of cartridges installed in it, having wings. The novelty is in the fact that the inner surfaces of the magazine wings are made at an angle to the respective side wall of the magazine determined by formula: alpha = arctg(L-d)/2Z, where alpha - the angle on inclination of the inner surfaces of the magazine wings to the respective side wall of the magazine; L - the width of the magazine inner cavity, mm; d - the diameter of the cartridge in its bottom part, mm; Z - the distance from the cartridge bottom part installed in the magazine wings on the rimming line to the point of intersection of the bore line with the plane of the breech face, mm. EFFECT: enhanced stability of weapon operation. 4 dwg |
