Otis 5.56mm Chamber Brush FG-367 HT Bronze/Steel

The Otis FG-367 HT is a chamber brush for cleaning the chamber of 5.56x45mm NATO rifles, including M-16, AR-15 and M4 platforms. It is designed to scrub carbon and fouling from the chamber area, where residue collects after firing.

The brush uses bronze and steel bristles and has a #8-32 thread pitch, so it attaches to standard #8-32 cleaning rod systems. It is sized for the 5.56mm chamber.

Use it with a compatible cleaning rod and solvent as part of routine bore and chamber maintenance.
