Note on Colored Anodizing:
Colored anodizing is an electro-chemical process and natural variations should be expected. Due to differences in alloy, forging, and dye uptake, slight shade mismatches between the upper, lower, and handguard—as well as visible blending, tonal variation, or minor surface marks—are inherent to the process and not considered defects. Color may also appear different under various lighting conditions.
