That, Is a very impressive piece of work (Art Actually) congratulations! So inquiring minds want to know Details, Details? Also will a side lever be in the future? Looks like it was designed to be an easy install of one.
The photo with three guns are Colibri 1 with custom made stock, than Mad Jumbo prototype with bottle and pre serial Colibri 2. It is just for comparison of look and size when I had all guns at once
The serial Mad Jumbo looks the same as on My latest photos. With piccatiny rail under the cylinder. Looks heavy but it weights only 3 kilos This is the final look of the stock, but You can always add gun sling swivels for better carry. It is easy to adjust the HST at the back, yes. Also You can change the plenum size and regulator pressure for velocity tuning. The long version can do about 310m\s with JSB 1.645. The barrels are Alfa Precision.Â
We have just started production here in Russia. But We will think about expanding to other markets
To reload this airgun You have just to pull action handle back and release it. It is the best way of reloading for Me, even after comparsion with side lever on FX Impact Aiming, shooting and reloading without changing the hold of a gun. Also We added the possibility to change the action handle side for left-haded people.
Feel free to ask any questions. I will be adding fresh information when I have any
