• Grinding + Lapping – For precision fit and consistent shot patterns.
• Nickel Plating (Niplate HV500) – Internal finish reduces fouling and corrosion.
• Chroming/Burnishing – Adds external toughness and polish.
• DLC Coating (Diamond-Like Carbon) – Enhances hardness (2500–3000 HV), reduces glare, and provides anti-friction properties.
