Hatsan is currently made in Turkey. They make this rifle in both .177 and .22 caliber. Unfortunately their homepage doesn't list the range of the rifle only the speed of the pellet. .177=1000 FPS and .22=750 FPS. You can try to contact them directly and ask customer service to give you an answer. The instruction manual says nothing about range.
