摘要： A buffer tube insert includes an elongated portion and one or more projections extending from the elongated portion. The one or more projections are configured for insertion into one or more corresponding notches on a buffer tube. Each projection includes a connection arrangement such as, but not limited to, a threaded interior for receiving a connection member such as, but not limited to, a set screw that can facilitate the restriction of movement between the buffer tube and a gunstock.

摘要： A semi-automatic or automatic rifle comprising a barrel attached to and upper receiver and including a compressible bolt carrier extension system. The compressible bolt carrier extension system includes a bolt carrier, an extension spring, two pins, and a reciprocation bolt carrier extension piece. As a whole, the compressible bolt carrier extension system makes possible the use of elongated upper and lower receivers to be used for chambering long-action or other center fire cartridges for use with AR rifles such as the M-16, and M4 etc., eliminating the need for any buffer or buffer tubes other than those commercially available. A further advantage of the compressible bolt carrier extension system is the reduction of felt recoil as the system fully loads during the recoil stroke as it pushes against the buffer absorbing additional recoil energy. The system can be incorporated into firearms using a variety of cartridges.

摘要翻译： 一种半自动或自动步枪，包括一个连接到上接收器的筒体，并包括一个可压缩的螺栓承载件延伸系统。 可压缩螺栓承载件延伸系统包括螺栓承载件，延伸弹簧，两个销和往复螺栓承载件延伸件。 总的来说，可压缩的螺栓承载架延伸系统使得可以使用细长的上部和下部接收器来放置用于与诸如M-16和M4等的AR步枪一起使用的长效或其它中心消防盒， 不需要任何可商购的缓冲管或缓冲管。 可压缩螺栓托架延伸系统的另一个优点是当系统在反冲冲程期间完全负载时减小毛毡反冲，因为它推动缓冲器吸收额外的反冲能量。 该系统可以使用各种墨盒并入火器。

摘要： To prevent inertial forces from inadvertently releasing the slide of a semi-automatic pistol into battery, a slide stop retention mechanism is mounted on the frame. A finger extends from the mechanism and pivots under the force of a biasing spring into engagement with the slide stop when the slide is in the open position. The finger supports the slide stop. A force applied to the slide stop, either manually or via a cam on the slide when the slide is pulled back and released, will move the finger out of its supporting position and allow the slide to move to battery.

摘要： A firearm including a barrel having a chamber and an integrally formed upper receiver having a passageway, an accessory rail extending the complete length of the upper receiver, and a guidance feature extending along the passageway. The firearm also includes an operating rod having an anti-bounce mechanism, a bolt that is rotated counter-clockwise to lock against the chamber, a bolt carrier having a safety extension disposed below the bolt that prevents a hammer from striking a firing pin until the bolt is locked against the chamber, a lower receiver, a recoil spring assembly, and a fire control group. The bolt includes a polymer spring that biases a sliding extractor against the base of a cartridge. The sliding extractor is disposed at an angle ranging from thirty degrees to fifteen degrees on the bolt face to provide a low ejection angle from the firearm.

摘要： An anti-recoil system for counteracting recoil in firearms and weapons using a gas actuated piston assembly is disclosed. A recoil piston is acted upon by gas pressure routed from the receiver/barrel. High pressure gas causes forward movement of the recoil piston thereby generating a force opposing the recoil generated upon firing. A shock absorbing bumper connected to the piston engages the weapon's rearwardly moving bolt assembly. The bolt assembly forces the recoil piston rearward and compresses the bumper and expanded gas in the recoil piston chamber thereby absorbing additional recoil forces. Upon reaching a rear most position a gas relief valve is opened allowing venting of the compressed gases at which point the bolt operating main spring propels the bolt assembly forward, stripping the top round out of the ammunition magazine, loading the next round, locking the bolt and freeing the firing pin to fire the next round. An electrical generation system designed to meet the current and future needs for individual combatants utilizes hereto fore wasted energies produced in the firing of a modern weapon. Specifically it is designed to convert the wasted energy contained in the ejected high pressure gasses and the subsequent recoil produced by the gasses accelerating a projectile to high velocities, and the energy contained in the rapidly moving bolt assembly. This energy is capable of being stored within the weapon, or in external, individual battery packs.
摘要翻译： 公开了一种用于抵消使用气体致动活塞组件的火器和武器的后座的反冲系统。 反冲活塞由从接收器/枪管路由的气体压力作用。 高压气体引起反冲活塞的向前运动，从而产生与点火时产生的反冲相反的力。 连接到活塞的减震保险杠与武器的向后移动的螺栓组件接合。 螺栓组件迫使反冲活塞向后，并且在反冲活塞室中压缩保险杠和膨胀气体，从而吸收额外的反冲力。 在达到最后位置时，打开气体释放阀，允许压缩气体排出，此时螺栓操作主弹簧向前推动螺栓组件，将顶部圆形从弹药盒中取出，装入下一个圆形，锁定螺栓 并释放射击针以触发下一轮。 旨在满足当前和将来对个别战斗人员的需求的发电系统利用了在现代武器射击中产生的浪费的能量。 具体地说，它被设计成将排出的高压气体中所含的浪费的能量以及由气体产生的后续反冲转换成高速度，以及包含在快速移动的螺栓组件中的能量。 该能量能够存储在武器或外部单独的电池组中。
