The Otis FG2715 Star Chamber Cleaning Tool is purpose-built to address one of the most commonly neglected—and hardest to reach—parts of your 5.56mm rifle: the star chamber. After a range session or hunt, powder residue and carbon buildup accumulate in those sharp recesses, and a standard brush or patch can't touch them. This steel cleaning tool with its included pads gets into those tight spaces fast, so you can maintain chamber concentricity and reliability without hours of frustration.

The tool's parkerized steel construction resists rust and handles repeated use. The 8-32" thread means it fits standard cleaning rod systems you likely already own, making it a logical addition to your existing Otis kit or any modular cleaning setup. It's not flashy—it's just effective, which is exactly what you want in a maintenance tool.

Whether you're a serious long-range shooter, a defensive rifle enthusiast, or a hunter who runs a tighter maintenance schedule, keeping your chamber clean pays dividends in consistency and longevity. Six cleaning pads ship with the tool, so you have enough for multiple sessions before you need to restock—and replacement pads are widely available and inexpensive.
