US Patent 12274807 Summary

• Title: Firearm trigger mechanism
• Assignee: ABC IP LLC
• Inventor: Mladen Thomas Strbac
• Filing Date: 2024-05-16
• Issue Date: 2025-04-15 (This is the publication date for the granted patent, which serves as the issue date)
• Abstract: A trigger mechanism for AR-pattern firearms features a hammer, trigger member, disconnector, locking member, and a three-position safety selector (safe, standard semi-automatic, and forced reset semi-automatic). In standard semi-automatic mode, the bolt carrier's rearward movement pivots the hammer, allowing the disconnector hook to catch the hammer hook, requiring the user to manually release the trigger to reset. In forced reset semi-automatic mode, the bolt carrier's rearward movement forces the trigger member to the set position, with the safety selector preventing the disconnector from engaging the hammer. This allows the user to fire another round without manually releasing the trigger once the bolt carrier is in the battery position. A locking member mechanically blocks the trigger from releasing until the bolt carrier is substantially in battery, preventing premature hammer release.

Plain-Language Overview of Independent Claims:

Claim 1 (Independent Claim):
Claim 1 describes a firearm trigger mechanism designed for a receiver's fire control pocket. It includes:

• A Hammer: This component pivots to strike the firing pin. It has a "sear catch" and a "hook." When the bolt carrier moves backward, it pushes the hammer backward.
• A Trigger Member: This is the part a user pulls. It has a "sear" that engages the hammer's sear catch when both are in their "set" (ready-to-fire) positions. During the hammer's rearward movement, it physically contacts a surface on the trigger member, forcing the trigger member back to its set position.
• A Disconnector: This part has a hook that typically catches the hammer hook after a shot in standard semi-automatic fire. It pivots on the same axis as the trigger member.
• A Locking Member: This component moves between two positions. In its first position, it physically stops the trigger member from moving to the "released" (fired) position. It's spring-biased to stay in this blocking position. However, when the bolt carrier moves fully forward to the "in-battery" position, it contacts the locking member, moving it against its spring bias to the second position, which unblocks the trigger.
• A Safety Selector: This offers three positions: "safe," "standard semi-automatic," and "forced reset semi-automatic."
  • In Standard Semi-automatic: When the bolt carrier moves backward after firing, the disconnector catches the hammer. The user must then release the trigger (allowing it to move forward) for the hammer and trigger to reset, enabling the next shot.
  • In Forced Reset Semi-automatic: When the bolt carrier moves backward, it forces the hammer and consequently the trigger member back to their set positions. Crucially, the safety selector's position in this mode prevents the disconnector from catching the hammer. Therefore, once the bolt carrier returns to its in-battery position, the user can immediately pull the trigger again to fire, without needing to manually release finger pressure on the trigger.
