Otis Technology Star Chamber Cleaning Tool – 5.56/.223

The Otis Technology Star Chamber Cleaning Tool removes carbon buildup from the star chamber and locking lug recesses of AR-15 and M16 rifles—areas standard brushes can't reach effectively. The tool's eight radiating fingers scrape deposits from the chamber's feed ramp transitions where carbon accumulates and causes extraction failures. Takes 30 seconds to use between range sessions or during field maintenance.

Compatible with 5.56 NATO and .223 Remington chambered rifles. Fits onto standard cleaning rods or can be used by hand. Reinforced molded construction stands up to repeated use without deforming the critical star pattern geometry.
