ALL-WEATHER GUN LUBRICANT OIL - Gun Butter’s Pen Oiler not only makes your gun more durable, but it also lubricates your gun properly to ensure optimal performance every time you clean it! The all-weather lubricant will not burn up or evaporate in summer’s heat; it functions normally in freezing weather and salt air, stays intact during pouring rain, and repels dust and airborne sand in dry conditions which cause wear and failure. It also inhibits corrosion, preventing the formation of rust.

ENHANCED FOR EXTREME TEMPERATURES - The most advanced lubricant for heavy weaponry, as well as your pistol, handgun, rifle, shotgun or firearm of your choice, Gun Butter Oil is not grease, but a gun lube and cleaner that has enhanced lubricity for extreme temperatures and humidity; its oil will resist change and perform consistently below -20 degrees to over 400 degrees Fahrenheit. Gun Butter’s smoothness and consistency is unmatched due to its ease of function.

BREAK IN PROTECTION & CLINGABILITY - Ideal for armed forces, police, and top shooting professionals, this high-performing gun lubricant gives break-in protection and clingability (film strength) to maintain its placement. Gun Butter’s gun lubricant cleans, lubricates, and protects metal from rust, moisture, and dramatically reduces wear during all shooting conditions. Gun Butter provides the maintenance your gun needs so that you can use it for a longer period of time.
