A rifle has a fixed main body, including a barrel, a receiver with an upper opening, a breech element, and a trigger assembly at least partly accommodated in the receiver. The rifle has a slide assembly including a shutter group positioned on the receiver at the upper opening and axially movable by the user between an advanced shooting configuration and a retracted rearming configuration, and vice versa. The rifle includes a recoil group at least partially accommodated in the receiver, for cooperating with the slide assembly having a thrust device with a thrust lever, which is rotationally movable and a thrust spring, which performs torsional action on the thrust lever. The thrust lever extends between a lever upper end and a lever lower end. The lever upper end is suitable engageable with the advancing slide assembly to push it into the advanced configuration.

A buffer tower for a rifle includes a cut-out on an upper end thereof. The cut-out extends a travel length of the bolt during bolt action. The cut-out extends the travel length by greater than 10 mm. This extended travel length reduces the felt recoil of the rifle and increases the cycle time. An increased cycle time improves feeding reliability from the magazine.

A firearm support system (FSS) includes a buffer tube mount (BTM) having a first complementary component and a receiver comprising a second complementary component configured to selectively receive the first complementary component. The BTM comprises a shelf that extends from a ring of the BTM.

A linear-to-rotary converter assembly includes a housing having a first portion, a second portion, and a bore in which a plunger is slidably disposed. The plunger includes a plunger body having threads and a plunger boss extending from the housing. At least one of a one-way bearing or a disk is disposed within the housing bore. A rod is disposed within the housing bore and has a first portion having threads engaging the plunger threads and a second portion extending through the at least one of the one-way bearing or the disk. At least one magnet is disposed within the housing adjacent to the one-way bearing or the disk. Linear movement of the plunger between a firing position and a recoil position rotates the rod and the one-way bearing or the disk in a first direction as the magnet acts on the at least one of the one-way bearing or the disk.

The present invention relates to a receiver stabilizing fixture for use with the receiver of a firearm. The stabilizing fixture interfaces with bracketry or a pre-existing element of the firearms design. The stabilizing fixture is mounted to the firearm through means common to the art, such as pins or screws. The stabilizing fixture allows for recoil forces to be better distributed in the firearm. This reduces wear on recoil sensitive parts.

An upper receiver is disclosed. The firearm contains a bolt carrier assembly positioned within the upper receiver, a recoil spring guide rod, wherein the bolt carrier assembly is configured to slide along the recoil spring guide rod between a locked position and an unlocked position, and a first recoil spring, wherein the recoil spring guide rod is positioned within the first recoil spring.

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.
