Firearm safing assemblies and firearms including the same are disclosed. In embodiments firearm safing assemblies include a safing sector with a track surface and a receiver door track. The receiver door track may couple to a receiver of a rotatable firearm, wherein the receiver includes a bolt track and at least a portion of the receiver extends coaxially about a first axis. The safing sector is configured to be at least partially disposed within the receiver door track and to move between a safe position and an armed position. In the safe position the track surface is out of alignment with and does not form part of the bolt track, whereas in the armed position it is aligned with and forms part of the bolt track.

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.

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 targeting system comprising a helmet, primary firearm, and secondary firearm. The helmet includes a helmet display. a primary firearm comprising: a receiver, a primary barrel, a primary camera, a swivel control, a first mounting point, a first display, and a second display. The secondary firearm includes a camera and a secondary barrel. The computing device comprises an user interface. The control circuit is coupled to the helmet, the firearm apparatus, and the user interface. The primary barrel is functionally coupled to the receiver. The helmet display is a heads-up display. The swivel control is functionally coupled to the secondary firearm. The secondary firearm is rotatably coupled to the first mounting point. The control circuit is configured to capture and convey images and video; receive a targeting instruction on the secondary firearm from the user interface; and instruct the swivel control to acquire a sight picture.

A separate-loading firearm uses a battery-powered electric resistance heating element to ignite a propellant charge. Both ignition reliability and ballistic reproducibility are enhanced when a first portion of the propellant charge is consistently and firmly packed into a cavity formed in a rear surface of a bullet. This first portion may be sealed in the cavity by a membrane. A second portion of the propellant charge is packed within a firing chamber so that it abuts both the heating element and the first portion of the propellant charge.

A separate-loading firearm, which may be configured as a muzzle-loading pepperbox pistol, uses a battery-powered electric resistance heating element to ignite a propellant. A relatively long current pulse, which may be of controllable duration, is used to ignite the propellant and a much shorter pulse may be used to test the integrity of the heater. Detection of the firearm's recoil may be used to terminate the relatively long firing pulse, which can increase the service life of the heating element and reduce the current drain from the battery.
