A bolt action rifle having a receiver; a bolt in slidable communication within said receiver, having an elongated body and a bolt head at a first end, and an exposed bolt face with a primer recess cavity having a base with a forward-facing surface, the base having an aperture therein, where the aperture is circumscribed by the forward-facing surface for receiving a propellant charge having an extended primer cap, and a firing pin within the bolt and movable between a disengaged position wherein a firing pin head is receded within the aperture and an engaged position wherein the firing pin head extends beyond the forward-facing surface into the primer recess cavity.

A break-action firearm for high caliber ammunition is described. In some arrangements, the firearm is a rifle. The higher caliber ammunition may be, for example, fifty caliber ammunition. The firearm includes a barrel that is hingedly coupled to a lower portion of the firearm. A latching mechanism secures the barrel in a firing position and releases the barrel from the firing position. The barrel includes a screw-on breech cap that is threadedly coupled to the end of the barrel. The breech cap includes a firing pin. When an ammunition cartridge is loaded into the barrel, the screw-on breech cap is installed, and the barrel is secured in the firing position, a user can pull a trigger that causes a firing hammer to hit the firing pin thereby firing the ammunition cartridge.

Muzzleloader systems include a pre-packaged propellant charge and primer for providing efficient loading and unloading of the muzzleloader. The muzzleloader accepts in the breech end the propellant containment vessel that abuts against a constriction portion with a reduced diameter portion. The propellant containment vessel having an end portion with a tapered surface that conforms to the constriction portion surface. A projectile is inserted in the muzzle end and seats against the constriction portion. The propellant containment vessel may be received in a removable breech plug. The constriction portion may be part of the breech plug or a separate component secured in the barrel by way of the breech plug. The containment vessel further comprises a primer mechanism that may be integrated into the proximal end of the containment vessel.

A flare gun with a barrel configured to be released in a horizontal direction is described. In embodiments, the horizontally opening barrel provides greater accuracy and ease of mounting additional equipment to the flare gun. In embodiments, the horizontally opening barrel also includes an in built extractor system to automatically extract the spent shell casings as the barrel is released. A compact and reliable hammer arrangement has been disclosed that provides better protection against rust and is hence more suited for marine applications. This hammer arrangement can be employed in either a horizontal or vertical barrel configuration. Additionally, extractor systems and barrel release systems to be employed in either a horizontal or vertical barrel configuration are described.

A firearm with tilting barrel-receiver assembly includes a frame and a barrel-receiver assembly pivotably mounted to the frame. The barrel-receiver assembly is movable between an open position and a closed position. A latching mechanism includes a latch that selectively engages the barrel-receiver assembly. The latching mechanism may be disposed in the frame in one embodiment. The latching mechanism is movable between a locked position wherein the barrel-receiver assembly is held in the closed position and an unlocked position wherein the barrel-receiver assembly is movable to the tilted open position. The latch may be spring biased into the locked position. The barrel-receiver assembly may be configured for complete removal from the pistol in some embodiments. An interlock mechanism formed by a movable safety may be provided which prevents the barrel-receiver assembly from being unlocked when the firearm is in a ready-to-fire condition.
