Abstract: A trigger mechanism that can be used in AR-pattern firearms has a hammer, a trigger member, a disconnector, a locking member, and a “three position” safety selector having safe, standard semi-automatic, and forced reset semi-automatic positions. In the standard semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer such that the disconnector hook catches the hammer hook, at which time a user must manually release the trigger member to free the hammer from the disconnector to permit the hammer and trigger member to pivot to the set positions so that the user can pull the trigger member to fire the firearm.

Abstract: A trigger mechanism having a hammer, a trigger member, disconnector, movable ejector lever, locking member, and safety the trigger member. The trigger member being forced to the set position by the hammer during rearward pivoting. A locking member is adapted to move between a first position at which the locking member mechanically blocks the trigger member from moving to the released position and a second position at which the locking member does not mechanically block the trigger member allowing the trigger member to be moved to the released position. The locking member is spring biased toward the first position and moved against the spring bias to the second position by contact from the movable ejector lever during forward movement of the bolt carrier as the bolt carrier reaches a substantially in-battery position. The safety selector is adapted to pivot between safe, standard semi-automatic, and forced reset semi-automatic positions.

Abstract: A trigger mechanism that can be used in AR-pattern firearms has a hammer, a trigger member, a disconnector, a cam, and a “three position” safety selector having safe, standard semi-automatic, and forced reset semi-automatic positions. In the standard semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer and pivoting of the cam from a first position to a second position such that a cam lobe forces the trigger member towards the set position, but prior to reaching the set position the disconnector hook catches the hammer hook, at which time a user must manually release the trigger member to free the hammer from the disconnector to permit the hammer and trigger member to pivot to their set positions so that the user can pull the trigger member to fire the firearm.

Abstract: In a forced rest trigger mechanism, provided is an extended trigger member locking device having a locking member that is movable between a first position in which it locks a trigger member against pulling movement and a second position where it does not restrict movement of the trigger member. The locking member is configured to be movably supported by a frame and includes a generally upward extension portion configured to make actuating contact with a surface of a bolt carrier. The locking member has a body portion that is movably supported and an upward extension portion that is separately movable relative to the body portion between an extended position and a deflected position.

Abstract: Provided is a trigger mechanism for a firearm having a receiver with a fire control mechanism pocket and a bolt carrier that reciprocates to pivotally displace a hammer when cycled. It includes a hammer having a sear notch and mounted in the fire control mechanism pocket to pivot on a transverse axis between set and released positions. A trigger member has a sear and is mounted in the fire control mechanism pocket to pivot on a transverse axis between set and released positions. The trigger member has a first surface positioned to be forcibly contacted by the hammer when the hammer is displaced by cycling of the bolt carrier, the contact causing at least in part the trigger member to be forced to the set position.
