F-1 Firearms' Color Anodizing Disclaimer: We at F-1 Firearms and our 3rd party anodizing partner try our very best to ensure the highest in quality with regards to our color anodizing. However, our color anodizing is low end Type III (0.0002" – 0.0012” in thickness) which can only be expected to withstand normal wear and tear and F-1 Firearms cannot be held liable for longterm fatigue. The color anodizing process is not a 100% color match every time thus it is expected that their will be some slight color variations in the anodizing and F-1 Firearms cannot be held liable for said variations.
