A firearm platform and method of connecting an upper receiver to a lower receiver. The upper receiver has a pivot lug and a takedown lug with perimeter openings in opposite directions. The lower receiver has a locking member that pushes against the takedown lug which causes the upper receiver to displace forward. As a result of the forward displacement, a pivot pin in the lower receiver exerts an opposing force against the pivot lug. The locking member is displaced between a locked and unlocked position through a lever located on an exterior surface of the lower receiver. When the locking member is in the locked position, the lower receiver and uppers receiver form a connection that is tight and free from slop.

A handguard is for a firearm having a firearm upper. The handguard includes a body and a cam. The body is structured to be coupled to the firearm upper. The body has a central lumen having a longitudinal axis. The cam may be coupled to the body in substantially perpendicular alignment to the longitudinal axis and is configured to rotate between an UNLOCKED position and a LOCKED position. When the cam rotates from the UNLOCKED position toward the LOCKED position, the cam rotates into the central lumen.

A breech block with a bolt carrier, on which a bolt head and a locking device are arranged with two diametrically opposed locking elements pivotable from a release position to a locking position via a control element, for holding the bolt head in a locking position. The locking elements are mounted pivotably around a common transverse axis via journals and the control element contains front and rear support areas that abut against the locking elements for controlled forced movement of the locking elements into both the locking position and the release position.

A receiver assembly for a handgun. The receiver assembly includes a receiver having a magazine well, a locking device having a locking lever for actuating the locking device, a control block accommodated in the receiver, a trigger pivotable in the receiver and about a trigger axis, a sear bar coupled to the trigger, a locking bar having a guide lug, and a lowering component accommodated in the control block, which has a bar guide slot formed therein. The sear bar extends to the control block and includes a guide bracket. The locking bar interacts with the locking device. The lowering component is displaceable for removing the slide assembly from the receiver assembly. The lowering component includes a control window and a guide link. The guide bracket is guided in the control window. The guide lug protrudes into the guide link and through a bar guide slot of the control block.

A hydraulically dampened rotary barrel locking system for a handgun is provided which preferably includes a receiver, a barrel and a spring-loaded moveable slide. The barrel comprises one or more axially aligned locking lugs configured to allow the slide to travel down the barrel axis when the lugs align with a keyway slot in an extended lug boss at the discharge end of the slide. Felt recoil is reduced and accuracy is improved due to a more balanced slide-to-barrel mass ratio than prior art and hydraulic dampening between the barrel and slide due to improved journal bearing action.

A magazine is provided for a firearm. The magazine comprises a locking mechanism. The locking mechanism has a user interface adapted to enable a user to select between a locked condition and an unlocked condition. The locking mechanism has a rotor movable between a first rotational position when the locking mechanism is in the locked condition and a second rotational position when the locking mechanism is in the unlocked condition. The magazine comprises an elongated shaft connected to the rotor. The magazine comprises a block element connected to the elongated shaft. The block element is adapted to move between a first position when the locking mechanism is in the locked condition in which at least one of firearm operation and magazine extraction are prevented, and a second position when the locking mechanism is in the unlocked condition in which firearm operation and magazine extraction are enabled.
