A firearm recoil buffer having a tubular body with a closed end, an open end, and an interior surface including an inset notch adjacent the open end. Fill material is provided in the tubular body to add a preselected amount of weight. A closure member has an attachment portion with a pawl portion that connectably engages the inset notch when the closure member is assembled by pressing into the tubular body.

Apparatuses, systems, and methods are provided for selectively changing the force required to cycle a firearm. In some embodiments, an apparatus is provided with at least two biasing members or springs where one biasing member generates a softer or smaller force than another biasing member. When manually cycling the firearm, the softer biasing member reduces the effort required for a person to cycle the firearm, which reduces the likelihood of injury and allows people with a broader range of physical abilities to cycle the firearm. Then, when the firearm fires a round, the other biasing member provides the greater force required to cycle the firearm in a conventional, semi-automatic or automatic manner.

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.

A device implementable in an AR-15 styled firearm includes a buffer tube and spring system and a bolt carrier assembly. The buffer tube and spring system is mounted on a lower receiver of the firearm and includes a pusher and a buffer tube which has a cavity that receives the pusher and the bolt carrier tail therein. The bolt carrier assembly includes a bolt carrier head and a bolt carrier tail connected to the pusher. The bolt carrier head includes a cavity that houses a bolt assembly of the firearm therein. The bolt carrier tail is elastically coupled to the bolt carrier head such that the bolt carrier head travels linearly at most by a first dimension, the bolt carrier tail travels linearly at most by a second dimension smaller than the first dimension, and the buffer travels linearly at most by a third dimension smaller than the second dimension.

A bolt catch device is disclosed. The bolt catch includes a movable surface configured to be positioned within a weapon so as to conditionally engage a bolt so as to prevent the bolt from rechambering a next round from a magazine, a tip configured to, in response to a received force, cause the movable surface to move so as to release the bolt, and a spring engagement feature configured to be positioned within the weapon so as to receive a spring within the weapon, wherein the spring within the weapon is configured to bias the movable surface toward a position which prevents the bolt from rechambering a next round.

The invention relates to the restructuring of the recolt guide (2) in order to prevent the firing line from deteriorating by reducing the impact force of the bolt (7), with the recolt spring (5) that is compressed during firing and moves back together with the bolt (7) returning to its original position, while minimizing the damage to the elements that make up the pistol.
