The Pro-Shot 30NCH .308 Cal. / AR-10 Military Style Nylon Chamber Brush is a dedicated rifle maintenance tool designed to clean carbon fouling, powder residue, and debris from rifle chambers and barrel extension locking lug recesses. Engineered for .308 Winchester and 7.62x51mm NATO platforms, this brush utilizes stiff, solvent-resistant nylon bristles wound onto a looped solid brass core with a brass coupling. This non-abrasive construction prevents scratching or gouging of critical chamber walls and headspace interfaces. Unlike phosphor bronze alternatives, the heavy-duty nylon bristles do not deteriorate when exposed to aggressive bore solvents and will not produce false-positive blue or green copper-solvent staining during chemical cleaning.

Key Features

• Solvent-Resistant Nylon Bristles: Heavy-duty, stiff nylon construction withstands aggressive chemical bore cleaners without material degradation or chemical-induced copper staining.
• Dual-Action Chamber Scrubbing: Military-style tiered profile scrubs both the main chamber body and the barrel extension locking lug recess areas.
• Solid Brass Core and Looped End: Brass core and coupling eliminate exposed sharp edges to safeguard headspace surfaces and chamber walls against mechanical scoring.
• Standard Thread Connection: Integrates directly with standard cleaning setups using an American standard male #8-32 thread.
