• an ammunition supply device mounted on said rotatable shaft to supply ammunition from said magazine to said predetermined position;
• a roller fixed to said at least one slide;
• primary guide means for positioning said at least one slide at a predetermined longitudinal position with respect to said weapon from a random longitudinal position with respect to said weapon, said primary guide means comprising a first ramp and a first counter ramp fixed to a recoiling part of the weapon, a distance between said first ramp and said first counter ramp decreasing towards said breech of said weapon to a length approximately equal to a diameter of said roller, said roller cooperable with said ramp and counter ramp to guide said at least one slide towards said breech;
• secondary guide means for positioning said at least one slide at a predetermined longitudinal position with respect to said magazine from a random longitudinal position with respect to said magazine, said secondary guide means comprising a second ramp and a second counter ramp fixed to said magazine, a distance between said second ramp and said second counter ramp decreasing towards said magazine to a length approximately equal to a diameter of said roller, said roller cooperable with said second ramp and said second counter ramp to guide said at least one slide towards said magazine.
