A hydraulic recoil device for a handgun or pistol is provided. The device includes a cylinder defining an interior hollow compartment having a first end and a second end. The device further includes a first resilient member; a piston assembly arranged adjacent to the first resilient member and at least partially within the cylinder, where the piston assembly includes a piston head, a piston rod, and a piston cap; a compressible accumulator arranged within the cylinder; and a second resilient member outside of the cylinder. When the piston rod is displaced toward the first end of the cylinder in operation, a hydraulic resistance is generated by the piston assembly, and when a first end of the second resilient member is displaced toward the second end of the cylinder in operation, additional resistance is generated by the second resilient member.

A trigger activated arm may use a piston moving within a cylinder to dampen gun bolt speed. In some embodiments, gun bolt motion increases pressure within the cylinder bore to dampen rearward gun bolt speed. The pressure may be high enough to unseat the cylinder creating a vent that cylinder fluid exits. In other embodiments, gun bolt motion decreases pressure within the cylinder bore to dampen forward gun bolt speed.

A recoil reduction device for a firearm is provided. The device includes a main body having a proximal end, a distal end, a first interior hollow compartment, and a second interior hollow compartment; a first recoil reduction assembly arranged at least partially within the first interior hollow compartment at the proximal end of the main body; and a second recoil reduction assembly arranged at least partially within the second interior hollow compartment at the distal end of the main body. The first recoil reduction assembly provides recoil reduction during a first stage of a firing cycle of the firearm, and the second recoil reduction assembly provides recoil reduction during a second stage of the firing cycle of the firearm, wherein the second stage is different than the first stage. The recoil reduction mechanisms provided by the first and second recoil reduction assemblies are different from each other.

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.

A fixed ejector is attached to the upper receiver, in combination with machining a slot into the carrier and the bolt, such that the ejector remains static such that, upon the bolt cycling, the spent shell casing contacts the ejector, causing it to be ejected out of the upper receiver.

A barreled firearm having a mass-locked breechblock and a recoil-damping element which is connected on one side to a frame assembly and on another side to a barrel assembly including a barrel. A housing part of the barrel assembly is mounted in the frame assembly in an axially slidable manner. A support element stationary relative to the barrel is mounted in a breechblock housing or in the frame assembly in an axially slidable manner. Alternatively, a support element stationary relative to the frame assembly is mounted in a breechblock housing in an axially slidable manner. The breechblock housing is guided by the frame assembly in an axially slidable manner and the breechblock housing is supported by the support element by means of a spring element. This design absorbs or reduces recoil when a shot is fired from the barreled firearm.
