Gemini Chokes

(Winshoot s.r.l.) has been producing choke tubes for several years, cataloging over 1.200 interchangeable choke tubes available in several materials, dimensions, finishes, and brands. This includes options for shotguns no longer on the market. Gemini emphasizes sport shooting in a variety of internationally recognized disciplines, particularly Trap, Double Trap, Skeet, Sporting, and Helice Shooting (Electrocibles or ZZ Birds).

Based in Italy, Gemini is atop producer in Europe with their products in use by many Olympic shooters. Gemini Chokes Turning and milling operations performed for the production of Gemini choke tubes are carried out using modern numerical control machines—very precise and reliable machinery. The whole process is steadily monitored with on-board machine control systems throughout manufacturing and at the end of the production cycle.

Particular attention is paid to finishes, including external grinding for less roughness and micrometric tolerances, and internal lapping to ensure that the choke performs the same sliding of the barrel. The bedrock of good choke tube performance is the materials they consist of.

Gemini chooses to manufacture its products mainly in 42Cr Mo4 steel alloy; approximately 80% of Gemini choke tubes are made of 42Cr Mo4 alloy steel (EN 10083-3), which is the most widely used steel in this field thanks to its excellent quality-to-price ratio and the right balance between hardness, mechanical strength, and toughness. AISI 630 steel, 17-4 PH stainless steel, is used for thinwalled chokes and they are not subjected to any subsequent Nickel or DLC coating but simply bleached.

Titanium (Ti 6AI-4V, grade 5) is used for specialized applications where very little weight at the muzzle end is necessary. These choke tubes are subjected to DLC coating. Gemini offers a program for retailers that want to distribute, import, or resell their products. Contact their sales team for further details at GeminiChokes.com, or call +39/030-675883.
