Breakthrough Clean Technologies® Chamber Mop — .223 / 5.56mm (AR-15), 79mm Length | Retail Packaging | Model BT-223CM-AR | UPC 855525007542 Speed up your AR-15 chamber cleaning and get a consistent, professional finish every time. The Breakthrough Clean Technologies Chamber Mop (.223/5.56mm) is purpose-built to reach—and thoroughly wipe—the locking lugs, shoulder, and chamber walls that typical patches miss. Measuring 79mm in working length and packed in retail packaging for clean storage, the BT-223CM-AR is the fast, reliable way to apply solvent, pick up residue, and leave a thin, even coat of oil in your 5.56 NATO / .223 Rem chamber. Why This Chamber Mop Belongs in Your AR Kit AR-specific reach: The 79mm profile is tuned for AR-15 chambers, contacting the shoulder and lug recess areas where carbon accumulates. High-absorbency fibers: Dense 100% cotton pile holds solvent and oil, lifting fouling and leaving a clean, uniform finish with fewer passes. Low-lint construction: Tight weave minimizes stray fibers so you don’t contaminate the chamber or barrel extension. Bore-safe & durable: Gentle on steel yet rugged enough for repeated use—wash, dry, and re-oil to extend service life. Retail-ready packaging: Keeps fibers clean and organized in your range bag or on a shop peg.

The BT-223CM-AR’s cotton pile increases surface contact for efficient solvent delivery and grime removal, helping you cut cleaning time while improving results. How to Use (Best Practices) Prep the chamber: After ensuring the firearm is unloaded, lock the bolt to the rear and remove the BCG and charging handle. Solvent pass: Lightly saturate the chamber mop with a quality solvent. Insert from the rear of the upper receiver and rotate through the chamber and lug recess. Agitate (optional): For stubborn carbon, use a chamber brush, then repeat with the solvent mop. Dry pass: Swap to a clean, dry mop to remove solvent and loosened residue. Protective film: Use a dedicated mop with a light coat of oil to protect the chamber; avoid excess oil that can migrate into the bore. Function check: Reassemble, cycle the action, and ensure smooth operation. Pro Tip: Keep two or three chamber mops on hand—one for solvent, one for dry passes, and one for oil. Label them to prevent cross-contamination. Ideal For Range days & classes with high round counts 3-Gun & carbine competition where reliability is critical Duty & defensive carbines needing quick, consistent maintenance Armorers and instructors servicing multiple rifles Care & Maintenance Hand-wash mops with mild detergent, rinse thoroughly, and air-dry completely. Store clean, dry mops in the original retail sleeve or a sealed pouch to keep dust-free. Replace when fibers become matted or absorbency noticeably declines. Compatibility Notes Verify thread size on your cleaning rod; use an adapter if needed. Safe with common CLP, carbon cutters, and copper solvents—always follow chemical manufacturer guidance. Use a chamber guide or rod guide where applicable to maintain alignment and protect the receiver.
