  • Patent number: 12188747
    Abstract: An accessory for a firearm includes a deflector integrated into the accessory and structured to alter a path of discharge gasses and/or debris after such gasses and debris are emitted from the firearm when the firearm is discharged. The deflector may be sized and shaped to alter a path of discharge gasses and/or debris after such gasses and debris pass a Loaded Chamber Indicator (LCI) of the firearm. The LCI indicates a presence of a cartridge within a firing chamber of the firearm, but openings within and around the LCI also provide a path for hot gasses and debris to strike accessories, which causes fouling and other deterioration.
