So i have a uuq 2.5x10x40 scope itbsighted in on my air venturi alpha but itvwont raise point of impacr on my talon ss same with my night crystal scope .this 2.5 inchs over the bore isnt cool wish i knew the talon ss wasnt sight in capable .oh most likely got a lemon air rifle .so paper weight its future sad a china made rifle is better than the american made one but airforce gets their parts from china the bolts are junk that come in the airforce rifle not american made just assembled in america big difference. Very disapointed a 300 dollar airrifle works where my airforce wont sight in .
