Birchwood Casey 44128 Synthetic Gun Oil 4.5oz Spout Can Lubricant

The Birchwood Casey 44128 Synthetic Gun Oil delivers superior lubrication and protection for all firearm types in a convenient 4.5-ounce spout can. This advanced synthetic formula penetrates metal surfaces to reduce friction while forming a protective barrier against corrosion and wear.

What Makes This Different

Unlike petroleum-based oils that can gum up over time, this synthetic formulation maintains consistent viscosity across temperature extremes from -40°F to 400°F. The oil's molecular structure bonds directly to metal surfaces, creating a longer-lasting protective film that won't burn off during rapid fire sequences. Standard gun oils often attract dirt and debris, but this synthetic blend repels contaminants while maintaining lubrication properties.

Key Features

• Synthetic formula resists breakdown and maintains viscosity in extreme temperatures
• Precision spout applicator allows controlled dispensing without waste
• 4.5-ounce capacity provides approximately 200+ applications for typical firearms
• Compatible with all firearm metals including steel, aluminum, and polymer components
• Non-toxic formula safe for indoor use with proper ventilation
• Displaces moisture to prevent rust formation in humid conditions
• Clear formula allows visual inspection of application coverage

Field testing demonstrates this synthetic oil maintains lubrication effectiveness through 500+ round count sessions without reapplication. The formulation excels in competitive shooting environments where consistent cycling is critical, while also providing long-term storage protection for hunting rifles and collection pieces. Salt air and humid conditions that typically cause corrosion are neutralized by the oil's moisture-displacing properties.
