Electroless Nickel Teflon has continually proven to outperform traditional Anodizing and Phosphate coatings by leaps and bounds! The increased reliability, corrosion resistance and ease of maintenance make this upgrade a no-brainer. PLEASE NOTE: These uppers are being sold at a discounted rate due to minor imperfection in the base metal. These imperfections are very common but are usually hidden when anodized. Nickel Teflon does not hide them as well. In no way shape or form will these blemishes affect functionality. Features: Forged & machined by Cerro Forge (Key Hole)
