ULTIMO AGGIORNAMENTO MARZO 2020
Perfect for sports shooting enthusiasts and professionals, they combine the whole Gemini's technology and know-how with the performance of this extremely light but extremely resistant material. We present our newest Gemini Ti 6Al-4V (grade 5) titanium alloy choke tubes.
As displayed in the previous articles, the Ti 6Al-4V (grade 5) is the most widespread and commonly used among the existing titanium alloys, as, thanks to its technical and mechanical characteristics, it is suitable to ensure performances very similar to steel, even though it boasts a much lower weight.
The mix of aluminum and vanadium is characterized by high tensile strength (1000-1200 N / mm²) and corrosion resistance, as well as excellent elasticity.
After months of research, hundreds of tests, trials and performance evaluations Gemini has succeeded in combining the best performance of its choke tubes with the lightness and comfort of an absolutely extraordinary material.
Why choose a titanium choke tube for your sports activities? The answer is really simple. Because it weighs less. This will allow you to better manage your shooting. How much less indeed? Regarding a Perazzi 4a gen. Bore 18,60 Ported 6, for instance the weight is 22.50g as for the titanium version, compared to 40.40g for the steel one. All things considered 45% less weight.
If you decide to mount a titanium choke tube, then, the crowned muzzle of your arm will be actually lighter.

After undergoing internal lapping and external grinding, any choke tube is marked with the lettering “titanium” and DLC coated (Diamond Like Carbon), i.e. the “Amorphous Diamond” layer providing additional hardness (2500-3000 Hv), extraordinary abrasion and wear resistance, a low frictional coefficient (smoothness and anti-adhesion) and excellent chemical inertness.
The entire production chain is 100% Italian ... Champions such as Alberto Fernandez, Diana Bacosi, and David Kostelecky have already shown great appreciation for the newest Gemini titanium choke tubes. A real satisfaction that we hope will increase the popularity of this real jewel of technology, enshrined in a few of grams.
