Birchwood Casey 44135 Synthetic Gun Oil 6 oz Aerosol Spray

The Birchwood Casey 44135 Synthetic Gun Oil delivers advanced lubrication and protection in a convenient 6 oz aerosol format. This synthetic formula penetrates metal surfaces more effectively than conventional petroleum-based oils, providing superior corrosion resistance and temperature stability.

What Makes This Different

Unlike traditional gun oils that break down under extreme temperatures, this synthetic formulation maintains viscosity from -40°F to 400°F. The aerosol delivery system ensures even coverage in hard-to-reach areas like bolt carriers and trigger mechanisms. The synthetic base provides longer-lasting protection compared to mineral oils, reducing maintenance frequency while extending firearm service life.

Key Features

• Synthetic formula resists thermal breakdown and oxidation
• 6 oz aerosol can with precision spray nozzle for targeted application
• Temperature stable from -40°F to 400°F operating range
• Displaces moisture and prevents rust formation on metal surfaces

Field testing demonstrates consistent performance across various conditions, from humid coastal environments to dry desert climates. Competition shooters rely on the consistent lubrication for rapid-fire sequences, while hunters appreciate the long-term protection during extended storage periods. The synthetic formula maintains lubrication properties through thousands of rounds without requiring frequent reapplication.
