Hatsan unleashes their multi-caliber monster, the Hydra! Utilizing their new Versi-Cal technology, the Hydra couples a barreled receiver in one of three calibers to a single rifle action. This allows the user to quickly change the barreled receiver via a single thumb screw located at the back of the breech. You can purchase different caliber barreled receivers separately and keep each caliber receiver scopes and ready to go. The system is so robust, it eliminates the need to re-zero each time a barrel is interchanged. It also allows shooters to use the rifle with commercially available crossbow arrows. This module features a hollow guide rod for the arrow to slide over. It accepts 20″ 2219 aluminum and carbon fiber arrows with a 0.30″ inside diameter.

The action is built on the tried and true Flash frame, which provides a powerful platform that small game hunters will love! The 165cc air cylinder fills to 200 BAR, and is capable of delivering up to 35 shots per fill in .177, 30 in .22 and 25 in .25 cal. The side bolt action is easy to operate, and the Quattro trigger is fully adjustable, allowing users to set it to their preference.
