The Diana Mauser AM03 is a sleek air rifle built for small game hunting. The air rifle version of the Mauser M03 hunting rifle features the 2-stage adjustable T06 trigger, along with a stock colored for hunting excursions. If you want to mount a scope, the 11mm dovetails will accommodate your optic of choice. Diana air rifles have an excellent reputation because of their durability and quality. They've kicked it up a notch with the N-TEC gas-piston powerplant! Diana's proprietary German Gas-Piston Technology delivers smooth shooting, dependability and a decreased cocking effort. There's no spring torque because there's no coiled metal mainspring!
