An armorer tool system for distributing the applied torque over a very wide surface, associated with assembling and disassembling primarily the barrel and the lower receiver extension of an AR platform firearms, independently of the specifications of their barrel extension, lower receiver and upper receiver external features, and magazine well geometry; and methods of using the tools are also disclosed.

Quick take-down firearms and methods of using quick-take down firearms. The quick-take down includes an upper receiver coupling and a barrel coupling. The quick take-down can be unlocked by sliding a sliding lock collar in a translational motion to an unlocked position to release locking elements from a locked configuration. In the unlocked position, a barrel and handguard may be installed onto and removed from the upper receiver of the firearm. Releasing the sliding lock collar returns it to a locked position, securing the barrel and handguard to the upper receiver.

The disclosure relates to firearms, and more particularly to a caseless weapon for magazine, semi-automatic and automatic shot. The disclosed weapon includes: a removable adjustable front sight, a removable adjustable dioptrical sight, a forward grip, a gunstock, a magazine, a receiver cover, a cocking lever, a bolt carrier, a rod, a percussion piston, a shutter housing, a safety catch of the firing percussion, a balancing gear, a barrel, a barrel latch, a multifunctional cartridge, a conical bushing of receiver, an extractor, a receiver, a big front nut, a front swivel, a magazine latch, a magazine latch pusher, a safety latch, a safety catch, a trigger bar, a bracket of the percussion mechanism, a cocking piece, a multifunction latch lever, a stop of the multifunction latch, a lock pin splint, a latch of the ramrod, a spring of the latch of ramrod, a ramrod, a caseless ammunition.

Pistols have a body having a grip, the grip defining a magazine passage, the body having a trigger guard defining a trigger space, the body having an upper surface, the body having a first mounting facility, an upper frame assembly removably connected to the body in a connected position, the upper frame assembly including a trigger element extending into the trigger space when in the connected position, a protrusion extending upward from the upper surface of the body, the protrusion having a forward-facing first bearing surface, and the upper frame assembly having a rear-facing second bearing surface adapted to abut the first bearing surface when in the connected position to transmit recoil forces from the upper frame assembly to the body. The upper frame assembly may have a slide rail. The upper frame assembly may define a horizontal slide plane.

An apparatus implementable on a firearm includes a quick-detach (QD) handguard assembly which includes a handguard and a locking mechanism. The handguard has a hollow therein allowing the handguard to surround a barrel of the firearm with the barrel traversing through the hollow along a longitudinal axis of the handguard. The locking mechanism is coupled to the handguard. The locking mechanism includes a QD lever configured to lock the handguard to a barrel nut of the firearm and unlock the handguard from the barrel nut.

A magazine limit block is provided having a base configured to fit within an interior of a magazine body and a tapered main body configured to guide and support a spring within an interior of a magazine body. The tapered main body extends upwardly from the base. A notch is formed at a top surface of the limit block and is configured to accommodate and provide space for a connection point of the spring and a follower. The main body is configured to occupy space within a magazine body to limit a number of rounds of ammunition that fit inside the magazine and guides the spring during cycling.

A firearm including a barrel bushing is disclosed. The barrel bushing provides for guidance of the slide without a need for forward rails. The barrel bushing is retained by a bushing stop that allows the slide to be removed while the recoil spring and bushing are retained on the barrel.
