Otis FG2715 Star Chamber Cleaning Tool 5.56mm 8-32 Thread Steel

The Otis FG2715 Star Chamber Cleaning Tool addresses the most challenging aspect of AR-15 maintenance by providing direct access to the star chamber area where carbon buildup compromises reliability. This precision-engineered tool eliminates the guesswork from cleaning one of the most critical yet difficult-to-reach areas of 5.56mm rifles.

What Makes This Different

Unlike standard cleaning rods that can't effectively reach the star chamber, the FG2715 features a specialized design that threads directly into the barrel extension. The 8-32 thread pattern ensures secure attachment while the steel construction withstands repeated use without bending or breaking. This targeted approach removes carbon deposits that traditional cleaning methods often miss, preventing the extraction failures and feeding issues that plague neglected rifles.

Key Features

• 8-32 thread pattern fits standard 5.56mm/.223 barrel extensions

High-volume shooters recognize the FG2715's value in maintaining peak rifle performance. Competition shooters rely on this tool to prevent the carbon-induced malfunctions that cost matches, while law enforcement armorers use it to ensure duty rifles function reliably when lives depend on them. The tool's effectiveness becomes apparent after extended shooting sessions where standard cleaning methods fall short.
