A NOTE FROM CEO, PHIL TYSON Firefly One Shot Gun Cleaner and Lubricant is becoming very popular with gun enthusiasts. After reading the reviews I decided to respond to them in this message. One-Shot Gun Cleaner and Lubricant is intended for the user that needs a quick, effective system to clean and care for their weapons. The intention was to provide a safe, bio-degradable, non-petroleum clean and effective product that makes maintenance of a weapon quick and easy. I do believe when an extremely dirty weapon needs maintenance Hoppes products will continue to be excellent even with the extra time spent using them. Personally, I have used One Shot in my AR POF 308. After a long day at the range, trying numerous different manufactures ammo, my AR was dirty and One Shot cleaned it quickly and efficiently. I bet my Army First Sergeant would have been pleased with the results. One Shot will make your cleaning time more efficient, safer and cleaner. Let me know your results in a review. Include a picture.
