Gemini Choke Optima HP Extended *Choose Choke Size – RATED FOR USE OF STEEL IN ALL RESTRICTIONS. Fits most later model Berettas A400, 686, 690, 694, DT11
The finishing is Gemini’s pride: grinding + lapping, and finally the surface treatments:
- “Niplate” (nickel HV 500) for the interior pieces to avoid oxidation and low friction.
- Chroming/burnishing for external pieces and internal/external pieces.
- 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 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 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 sliding of the barrel).
