A composite multi-lobe barrel is disclosed for directing the path of a dischargeable projectile. The multi-lobe barrel incorporates a plurality of longitudinal stiffening rods into a composite overwrap around an inner liner to enhance axial stiffness. The barrel is comprised of an inner liner defining an axial bore; a plurality of polymer matrix composite (PMC) stiffening rods equidistantly disposed around the inner liner and a PMC outer shell enclosing the stiffening rods. In one embodiment, a PMC inner wrap surrounds and is in direct contact with the inner liner, with the stiffening rods arranged equidistantly around the inner wrap, with this structure enclosed by a PMC outer shell.

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.

A projectile for use with a tapered gun bore having a tapered bore section between the breech and the muzzle. The projectile includes an elongated body having a cylindrical bulkhead with a diameter substantially equal to the large caliber section of the gun bore. A tapered ogive extends from the bulkhead to a front end of the projectile while a tapered tail extends from a rear end of the projectile to the cylindrical bulkhead. A plurality of circumferentially spaced forward grooves extend forwardly from the bulkhead and to a point short of the front end while a plurality of circumferentially spaced rearward grooves extend rearwardly from said midsection and to a point short of a rear end of the body.

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.

A rotation-force adjusting device for a toy gun has a pressing tube, an adjusting unit, and a gun body. The pressing tube has a pressing block, a cushion hole, and an abutting portion. The pressing block is formed on and protrudes radially inward from a top portion of the inner surface of the pressing tube. The cushion hole is formed through the top portion of the pressing tube. The abutting portion is formed at the top portion of the pressing tube and is formed on the pressing tube above the cushion hole. The adjusting unit is mounted around the pressing tube and has a force ring and a control knob. The force ring is mounted around the pressing tube, and the control knob is mounted through the force ring. The gun body has an inner barrel mounted through the pressing tube.
