How to Use (Quick AR Cleaning Routine)
Unload & Verify Clear: Remove magazine, lock bolt to the rear, and visually/physically check the chamber.
Solvent Prep: With a patch or the cotton mop, apply solvent from the chamber toward the muzzle (use a bore guide if available). Let soak briefly.
Scrub: Make 5–10 steady passes with the bronze brush to loosen carbon and powder fouling in lands and grooves.
Patch Out: Run dry patches until mostly clean.
Final Pass: Use the cotton mop to apply a light oil film for storage or to leave a dry, lint-free finish before zeroing or competition.
Performance Benefits You’ll Notice
Improved Reliability: A clean chamber and bore support consistent feeding and ejection.

Rinse After Use: Swish the brush in clean solvent; shake dry.
