Abstract

An accessory for a firearm includes a deflector structured 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.

Claims (27)

1. A firearm, comprising:

a Loaded Chamber Indicator (LCI) that indicates when a cartridge is loaded into a firing chamber of the firearm; and

a deflector structured to alter a path of discharge gasses after the discharge gasses pass the LCI.

2. The firearm of claim 1 , in which:

the deflector is part of an accessory; and

the deflector is structured to block a gas path between the LCI and the accessory.

3. The firearm of claim 2 , in which the accessory is a sight, and in which the deflector is structured to block a gas path between the LCI and a lens of the sight.

8. The firearm of claim 1 , in which the deflector does not interfere with an operation of the LCI.

9. The firearm of claim 1 , in which the deflector includes a scalloped shape structured to alter the path of discharge gasses.

10. The firearm of claim 1 , in which the deflector is formed from glass-filled nylon.

11. An accessory for a firearm that includes a Loaded Chamber Indicator (LCI) for indicating a presence of a cartridge within a firing chamber of the firearm, the accessory comprising:
