The Pro-Shot 5.56mm / .223 Cal. Military Style Nylon Chamber Brush is engineered for effective, non-abrasive cleaning of AR-15, M16, and M4 platform rifles. Its dual-purpose design cleans both the chamber and the star chamber (locking lug recesses), helping remove carbon, powder residue, and debris to promote reliable firearm operation.

The smaller forward brush reaches deep into the chamber, while the larger rear section thoroughly cleans the locking lug recesses where fouling commonly accumulates. Constructed with heavy-duty nylon bristles, this brush is highly resistant to wear and chemical breakdown from modern gun cleaning solvents and CLP, making it an excellent choice for routine maintenance and frequent cleaning.
