Abstract: A compact action for a firearm including an upper receiver housing incorporating a barrel. A bolt and supporting carrier is positioned within the receiver housing so that the bolt is engaged to a rear receiver end of the barrel in a cartridge chambering position. Guide rods are supported within the housing above the barrel and extend in parallel to a rear located end plate. The carrier includes a carrier key supported by and displaceable along the guide rods between the barrel and a rearward bumper component. A gas tube extends from a forward located gas block overlaying a gas discharge aperture in the barrel to a gas key for actuating the carrier rearwardly following discharge of a ballistic from the barrel. A charging handle is manually displaceable along a slot in the housing for actuating an interior slider component, in turn actuating the carrier key to cycle the carrier and bolt.

Abstract: A dual lever ambidextrous and reversible safety selector switch for a firearm having a central rotatable component pivotally mountable through a transverse directed aperture in a lower receiver of the firearm for selective rotation relative the receiver. First and second circumferential slots are configured within opposite sides of the component, each of the slots exhibiting a seating detent located at each of opposite ends so that a spring loaded detent pin in the lower receiver seats within one of the configured slots for displacement between the end detents between each of “safe” and “fire” configurations. At least one end face of the component has either a recessed or projecting shape with a pair of acute angled corners. A pair of control levers are provided, with at least one lever attaching to the end face of the component, so that either lever can be manipulated from either side of the lower receiver for actuating the selector.
