Diana 340 N_Tec Panther Cal. 177 air rifle

"The Diana Panther 340 air rifle is powered by German gas piston technology that offers consistent power and a decrease in vibration leading to better accuracy. Being a lightweight rifle, weighing only 3.5 Kg, it is relatively easy to cock for such a powerful break barrel. The T06 metal trigger lets you customize the trigger to your liking making this gun even more pleasing. Benefits of a gas-piston powerplant: Smoother cocking Smoother shooting No spring torque No spring fatigue, even if you leave it cocked for hours Functions perfectly in cold weather Lasts longer than a metal spring"
