A firearm security device includes a base assembly, a first plate connected to the base assembly, a retention post attached to the first plate, and a second plate. The first end of the retention post is connected to the first plate and the second end is configured to be inserted into a trigger well of a firearm. The second end includes a forward portion, a rearward portion, and a channel that separates the forward and rearward portions. The channel is configured to receive a firearm trigger. The second plate is moveable between an unlocked position and a locked position. The firearm security device includes a locking assembly that selectively locks and unlocks the second plate. The retention post is configured to transfer force away from the trigger guard and to the receiver in the event an external force is applied to a firearm locked between the plates.

The present disclosure relates to the technical field of special locks. The lock structure with improved safety includes a support assembly, a fixed cavity and an unlocking cavity; the fixed cavity is provided with a lock beam; the unlocking cavity is provided with a lockhole and a locking device; the lock beam is threaded into a trigger position of a gun and then into the lockhole and is locked by the locking device; an inner wall of the lockhole extends into the unlocking cavity to form a lockhole ring; a convex rib is arranged on an inner wall of the lockhole ring; a groove is formed in an outer wall of the lock beam; the convex rib and the groove are connected with each other in an embedded manner, so that the lock beam is stabilized in the lockhole ring.

The techniques described herein relate to methods and apparatus for firearm safety mechanisms, visual safety indicators, and related techniques. A firearm includes a handle comprising one or more buttons disposed at least partially within a surface of the handle, such that the one or more buttons can be in contact with an operator's hand when the operator grasps the handle; a safety mechanism in mechanical communication with the trigger. The safety mechanism comprises: a first position that blocks actuation of the trigger; and a second position that does not block actuation of the trigger; and at least one processor configured to: upon determining an input code matches a stored code, transmits a signal to the safety mechanism to change the safety mechanism from the first position to the second position so that the firearm can be fired by the operator.

A compression screw attachment system, including an attachment base having at least one projection, wherein an at least partially internally threaded compression screw recess extends from a terminal surface of the projection; at least one at least partially externally threaded compression screw, rotatable within the compression screw recess between a retracted position and an extended position; and one or more attachment elements, each having an attachment element recess, wherein a compression screw aperture is formed through the recess bottom wall, wherein if the compression screw is in the retracted position, the attachment element recess is slidably mateable with the projection of the attachment base and wherein the compression screw is threadedly rotatable to the extended position, wherein at least a portion of a head portion of the compression screw contacts a surface of the recess bottom wall and provides a force to urge the recess against the projection.

A selective fire firearm may be provided having a fully automatic open bolt and a semi-automatic closed bolt mode of operation. The firearm may include a trigger group having a trigger prop that ensures that, when the trigger is released in the fully automatic open bolt mode, the bolt carrier stops in an open bolt position held by an open bolt sear. The trigger prop may include a foot that, following a first trigger pull in the fully automatic open bolt mode, slides under and props a rear end of the trigger in a position that allows the open bolt sear to catch the bolt carrier when the trigger is released and propped but prevents the trigger sear from engaging the hammer.

An apparatus for adapting a clamshell-type of gunlock for a shotgun to lock a rifle. The clamshell gunlock can be easily modified using the apparatus without the need for basic changes to the gunlock. The apparatus has a single molded rubber part attached to the gunlock to hold the buffer tube of a rifle; providing a snug fitting constraint to hold the buffer tube of the rifle such that the rifle will not vibrate or move causing rattling sounds or damage to the rifle.
