摘要： A firearm as disclosures herein comprises a main receiver body, a barrel, a breech bolt structure, a buffer assembly, a trigger group assembly, a bolt catch and at least one of an auto-sear, a magazine adapter and a breech bolt anti-rotation structure. The main receiver body is preferably of a monolithic construction whereby the handguard and breech bolt carrying bore can be manufactured from a single piece of material. The auto-sear is tripped by engagement with a buffer of the buffer assembly. The magazine adapter has an exterior surface structure engaged with a mating interior surface structure of a magazine well space of the main receiver body. A distal end portion of the breech bolt anti-rotation structure is engageable by the buffer for limiting forward travel of the buffer when the barrel is detached from the main receiver body.

摘要： Applicants have disclosed an adjustable modular trigger assembly, and a related method, to avoid an unexpected firing of a long gun after an unintentional trigger pull. Applicants' preferred assembly comprises: a modular trigger housing, containing every trigger component, designed to be removably mounted within a lower firearm receiver; a trigger pull adjustment screw in a housing wall; and a sear force adjustment screw in another housing wall. During an intentional trigger pull, the shooter's finger pushes against a secondary trigger until it nestles within a slot of a non-coaxial primary trigger. Continued pulling on both triggers causes a sear to fall off a hammer notch and the firearm to discharge. In an unintentional trigger pull or jostling of the primary trigger, hooked protrusions (within the housing) of the second trigger and hammer engage to block the hammer from fully rotating, thereby avoiding discharge of the firearm.

摘要： 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.

摘要： Automatic bolt catch release apparatus for an open-bolt firearm of the type which includes a bolt catch to retain the fully-automatic bolt in open position upon firing the last round in a magazine. The bolt catch is released when the empty magazine is withdrawn from the firearm, so that the bolt can move forward into engagement with the sear to be maintained in a fireable open position. The firearm can then be fired as soon as a fresh magazine is provided.
