A new design for semi - automatic weapon for several tubes cartridges loading system for long guns, wherein an in-between connection steel part (11) fixes the barrel (3, 13) to the receiver (10). The retention of the cartridges inside the parallel tubes (45) is done by three metallic nails. The springs of the loading tubes push the cartridges into the cylinder (30) inside the gun through three openings made into the front side of the receiver (10) under the barrel. The rotation mechanism of the cylinder is a result of changing the movement of the bolt (14) from the horizontal into vertical.
