    Abstract: A smooth-bore barrel assembly including a first segment that extends downstream of a powder chamber, a bore followed by a segment having an increased diameter, and a final choke constituted by a first final portion and by a second final portion; the barrel is characterized in that the first segment has a divergent-convergent configuration, constituted by a divergent portion and by a convergent portion, or a solely convergent or solely divergent configuration. Advantageously, the barrel assembly can be provided in a modular form and includes three basic components: a barrel body, an extension, an inner choke member and/or an outer choke member.

    Abstract: Embodiments of the invention include a firearm system and method of assembly of the firearm system including a receiver complex including a receiver coupled to a forward receiver. A feed port is positioned between the receiver and the forward receiver, and a striker coil assembly is positioned proximate the receiver, and includes a plurality of strikers each extending at least partially through a coil. An interchangeable barrel is coupled to the forward receiver forming a breech. In some embodiments, the firearm system includes a breech that includes a plurality of side-by-side bores of the barrel. Some embodiments include a magazine coupled to the receiver complex adjacent the feedport to simultaneously feed more than one dischargeable projectile into the feedport with a single charge block. In some embodiments, the charge block includes a plurality of chambers and a plurality of projectiles positioned within the plurality of chambers.

    Abstract: The invention relates to safety components/modifications for a firearm barrel for preventing discharge of live ammunition from the firearm. The invention includes one embodiment of a modified barrel including a rod member transversely positioned within a portion of the bore of the barrel adjacent to the chamber to prevent chambering or loading of a live round. The modified barrel further includes a standard blank-firing adapter (BFA) fixedly coupled to the distal or muzzle end of the barrel.

    Abstract: A gun barrel for locking spin-stabilized projectiles using a driving band and a sealing ring disposed behind the driving band, the gun barrel comprising a breach area, a rifled barrel part, and a transitional cone disposed between the breach area and the rifled barrel part. In order to achieve a reliable initial seal between the projectile and the profile of the rifled barrel part against hot propulsion charge gases, a smooth barrel section is disposed between the transitional cone connected to the breach area and the rifled barrel part, wherein the interior diameter of the smooth barrel section is greater than or equal to the exterior diameter of the driving band, but is approximately equal to the exterior diameter of the sealing ring, wherein the length of the smooth barrel section corresponds to at least the lengths of the driving band and the sealing ring of the projectile.
