Made for Performance and Built to Last

Gemini chokes are precision-made in Italy using high-grade materials and state-of-the-art CNC machinery, trusted by both professionals and competition shooters.

• 42CrMo4 Alloy Steel – Strong, durable, and heat-treated for balance and toughness. Nickel-plated and DLC-coated for reduced friction and corrosion resistance.
• 17-4 PH Stainless Steel – Used for thin-walled chokes, this steel offers high strength and excellent corrosion resistance after precise heat treatment.
• Grade 5 Titanium (Ti 6Al-4V) – Ultra-light, strong, and corrosion-resistant. DLC-coated and ideal for shooters looking to reduce weight at the muzzle.

Advanced Finishes for Long-Term Reliability

Every Gemini choke is finished through a detailed multi-step process for optimal durability, smoothness, and protection:

• Nickel Plating (Niplate HV500) – Internal protection against oxidation and fouling.
• Chroming/Burnishing – External protection and refined appearance.
• DLC Coating (Diamond-Like Carbon) – Exceptional hardness (2500–3000 HV), abrasion resistance, and glare reduction with a slick, anti-adhesive finish.

Designed for Steel Shot Use

Laser-marked to indicate compatibility with steel or lead shot, each choke complies with Banco Nazionale di Prova steel shot standards.

Care Instructions

• Ensure the firearm is unloaded before fitting.
• Check the choke for damage before each use—do not use if threads or contact surfaces are compromised.
• Tighten the choke securely to prevent gas leakage.
• Clean regularly, and always apply high-temperature grease before reinstalling for optimal performance and longevity.
