The extractor engages approximately 17% more of a seated ammunition cartridge's rim as compared to the prior art AR15 / M16 extractor. The result is an improved bolt and bolt carrier which provides for increased operational reliability.

A firearm sight can detect engagement of a firing pin with a cartridge, and can respond to this event by saving an image which shows a target and reticle at a point in time just prior to the detected event. An electronic reticle can be downloaded into the sight. The effective position of the reticle within the sight can be adjusted electronically, and a zoom factor of the sight can be adjusted electronically. The sight can sense approximately transverse movement thereof, and can provide a user with an indication of the amount of transverse movement. With the use of an additional device, the sight can automatically align its reticle to the bore of a firearm on which the sight is mounted.

A shotgun comprises a receiver made from a first material; barrel having a portion extending into the receiver and made from a second material; a collar nut securing the barrel to the receiver; a bolt assembly disposed within the receiver and including a locking block configured to project into the barrel portion and lock the bolt assembly to the barrel prior to firing, the bolt assembly including a firing pin; and a trigger mechanism including a hammer for striking the firing pin.

A pistol including a mechanism that locks firing pin of the pistol. The firing pin locking mechanism may include a stopping member which may be selectively moved by a user of the pistol between first and second positions, and a movable blocking member that may be engaged with a forwardly-movable firing pin. A biasing member such as a spring may be provided to bias the blocking member into engagement with the firing pin. In one embodiment, the blocking member arrests or blocks the forward motion of the firing pin to prevent the firing pin from striking a loaded cartridge and discharging the pistol. In a possible first activated position, the stopping member prevents the firing pin blocking member from being operably disengaged from the firing pin, thereby preventing the firing pin from moving forward to strike a cartridge. In a possible second deactivated position, the stopping member allows the firing pin blocking member to be disengaged from the firing pin by normal operation of the pistol trigger system to allow the pistol to be discharged. The firing pin locking mechanism may further include a locking member to allow a pistol user to lock the stopping member in the first position or second position.

An improved bolt carrier for a firearm is provided that improves the overall reliability and performance of the firearm bolt assembly. The bolt carrier includes a bolt with a body having a number of lugs extending therefrom. The bolt includes an extractor recess sized and configured to avoid any undercut of the lugs adjacent the recess. The bolt also includes an extractor pivotably engaged in a recess formed in the bolt. The extractor has a pair nipples on flanges configured to engage a pair of integrally buffered springs disposed on a tapered spring well on either side of a firing pin bore extending through the bolt.

A firing mechanism for a firing pin striker operated semiautomatic handgun that includes a sear, a sear block housing, and a pivot arm. The sear is attached to the pivot arm and includes two angled surfaces and an edge portion for controlling the firing pin. The edge portion abuttingly engages an extension of the firing pin adapted to be in planar movement with the edge portion of the sear. The pivot arm and sear move together in an arcuate path about the pin in response to trigger firing movement. Unlike prior art firing mechanisms, the sear does not move vertically along an axis perpendicular to the bore of the handgun. The arcuate movement of the pivot arm causes the edge portion of the sear to disengage from the firing pin. The angled surfaces of the sear allow the firing pin extension to pass over the sear discharging the firearm.

A sear mechanism for firearms comprises a sear box 12, and an additional safety device to prevent the hammer 16 from releasing accidentally and to fire under the action of inertial forces acting along the direction of the axis of the barrel in case of impact of the firearm, the additional safety device being an interposing element 60 which is slidably mounted below the firing pin latch 43 in a housing having a first inclined plane element 63 and a second inclined plane element 63a which are arranged between lateral walls 62 to form a seat 61 which holds element 60 in a first position where it does not interfere with the operation of the firing pin latch 43 but allows said element 60 to move into a position where it prevents the pin latch 43 from moving downwardly to disengage hammer 16.

A firearm includes a frame and a slide. A firing mechanism for the firearm includes a striker-type firing pin, a trigger, and a trigger bar. A sear inside the frame is pivotally balanced about a central fulcrum, and is biased in a first pivotal direction by a spring. In this position, a rear portion of the sear engages the firing pin. Actuation of the trigger causes the trigger bar to move rearwards for engagement of a forward portion of the sear. This pivots the sear in a second pivotal direction, against the spring, which releases the firing pin. The spring then causes the sear to pivot back for reengaging the firing pin when it returns to its rear position. Movement of the slide to a retired position causes the trigger bar to disengage from the sear (preventing discharge of the firearm) until the slide returns to a battery position.

The present invention provides a handheld power tool having an impact block and an impact block return device. The impact block has a plurality of continuous teeth arranged along a lengthwise direction of the impact block. The impact block return device comprises a gearwheel engaged with the teeth of the impact block; a ratchet wheel rotating simultaneously with the gearwheel; and a clamping member operated in a first state and a second state, the clamping member contacting the ratchet wheel in the first state and the clamping member being separated from the ratchet wheel in the second state; wherein the impact block only can do a single-directional movement when the clamping member contacts the ratchet wheel in the first state. The present invention can improve stability of the retraction process of the impact block (e.g., a firing pin).

A closed bolt system with a trigger assembly for converting an open bolt, blowback type submachine gun into a single firing carbine is provided. The closed bolt system with trigger assembly includes a tensioned trigger member supporting a tensioned disconnector system. A tensioned sear interacts with the disconnector system and a tensioned hammer. The hammer strikes a firing pin in the bolt when it is released from the sear. The blowback of the bolt, as a result of expanding gases from the exploding and exiting round, re-cocks the hammer by re-engaging the sear with the hammer and disengages the sear from the disconnector system. Only after releasing the trigger will the sear re-engage with the disconnector system and thereby permit another round to be fired. A receiver having a cavity encloses the bolt and prohibits a fully automatic bolt to be used therewith.

A spike mold structure includes a first male mold base having a plurality of male molds and at least one firing pin, and a female mold base having a first fixing board, a second fixing board, a plurality of outer female molds and inner female mold. The second fixing board has at least one sliding rod, and the sliding rod has an actuating block. One surface of the first fixing board has a plurality of convex blocks. A plurality of concave slots are located at the surface of the sliding rod. The thimbles push the actuating block to make the sliding rod slidingly move so that the first fixing board and second fixing board are closely embedded or have a gap. Therefore, there is a displacement between the outer and the inner female mold. The spike mold structure is used to mold a bi-colored spike having increased strength.
