A man-portable gas-operated riot control weapon is provided in which the energy imparted to the round 29 on firing is automatically adjusted through a coupling to the range-finder sight (not shown) as the target is ranged. A chamber 24 in a cylinder 13 on one side of a piston 21 constitutes a variable volume accumulator, the position of the piston along the cylinder being adjusted automatically during ranging. After each firing, the accumulator is recharged from a gas bottle via a gas pressure regulator, charging taking place when the weapon is cocked. <IMAGE> |
