GEMINI CHOKE MOBIL MODIFIED EXTENDED 12GA

GEMINI CHOKE MOBIL MODIFIED EXTENDED 12GA

12 Gauge Gemini Choke Mobil extended choke – RATED FOR USE OF STEEL IN ALL RESTRICTIONS. Fits Franchi, Stoeger 2000/3000, earlier model Beretta & Benelli, Ranger M5, Dickinson, and most Turkish guns.

The finishing is Gemini’s pride: grinding + lapping, and finally, the surface treatments:
1) “niplate” (nickel HV 500) for the interior pieces to avoid oxidation and low friction.
2) chroming/burnishing for external pieces and internal/external pieces.
3) DLC (diamond-like carbon) coating. The DLC is a coating in “Amorphous Diamond”, providing the choke tube with additional hardness (2500-3000 Hv), extraordinary abrasion and wear resistance, and a low frictional coefficient (smoothness and anti-adhesion) and excellent chemical inertness.

Turning and milling operations performed for producing Gemini choke tubes, are carried out using modern numerical control machines, very precise and reliable machinery. The process is steadily monitored with scrupulous onboard machine control systems throughout the 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 barrel sliding).

The bedrock of the excellent performances boasted by Gemini’s choke tubes is the materials they consist of. Gemini has chosen to manufacture its products mainly in 42CrMo4 steel alloy, except thin-walled chokes, for which Gemini prefer 17-4 PH stainless steel.

Finally, for those looking for a product of the highest performance level with minimum weight in sport shooting, Gemini uses Ti 6AI-4V (grade 5) titanium.
