An electronic firing rifle assembly includes a salvo rifle operable through electrical means to efficiently discharge a salvo of projectiles. The assembly includes a firearm receiver body that provides housing for internal action components. The firearm receiver body has an inner surface defined by cam slots. The assembly also includes a barrel subassembly having a barrel and a plurality of barrel guide cams extending radially within the cam slots formed in the firearm receiver body. The assembly also includes a reciprocating bolt defined by has an ammunition placement zone for retaining ammunition, such as a tround. A leaf spring ejects the ammunition after discharge of projectiles. The bolt is defined by a cam track that allows the bolt to rotatably and longitudinally reciprocate along a bolt translation path in a helical path. Data pertaining to the location and direction of projectile discharge is transmitted for identifying discharge locations and tracking.

A reciprocating bolt assembly has delayed blowback and a firing pin block. Features prevent out-of-battery firing, when the bolt assembly is not fully engaged to the firing chamber or barrel face, a movable member within a bolt body functions as a blocking member that blocks the firing pin and prevents the firing pin from striking a cartridge. In embodiments, the firing pin has two stop portions that the movable member can engage depending on the cycle status of the firearm. A reverse cam mechanism associated with the firing pin blocking provides a resistance to and delays blowback.

A semi-automatic or automatic rifle comprising a barrel attached to and upper receiver and including a compressible bolt carrier extension system. The compressible bolt carrier extension system includes a bolt carrier, an extension spring, two pins, and a reciprocation bolt carrier extension piece. As a whole, the compressible bolt carrier extension system makes possible the use of elongated upper and lower receivers to be used for chambering long-action or other center fire cartridges for use with AR rifles such as the M-16, and M4 etc., eliminating the need for any buffer or buffer tubes other than those commercially available. A further advantage of the compressible bolt carrier extension system is the reduction of felt recoil as the system fully loads during the recoil stroke as it pushes against the buffer absorbing additional recoil energy. The system can be incorporated into firearms using a variety of cartridges.

The invention relates to an external chassis for a long firearm, the precision of which is increased owing to: 1. The incorporation of an external chassis, inside which the firearm is installed. 2. The anchoring of the firearm telescopically inside the external chassis using sliding rings with minimum friction. 3. The inclusion of a movement absorbing element. 4. The inclusion of guide bushings that limit the movement of the firearm to a single axis. With the above elements arranged as shown in the drawings, the inherent recoil produced in a firearm at the moment of firing, owing to the action-reaction effect of the stock-projectile assembly or the stock-discharge system, is suppressed and absorbed by the proposed invention, such that the stock remains immobile and no movement is transmitted to the shooter. As a result, precision is considerably increased and the optical sighting elements are not affected by sudden movements, thereby protecting these elements from possible damage and from being moved out of position. The elements described also ensure that the firearm moves only along the axis of the barrel, thereby guaranteeing precision. In addition, owing to the design of the invention, it can be incorporated not only into firearms having a specific new design, but also into existing firearms.
