Hello, i have a brend new 870 right out of the box that i was installing a set of adjustable fiber optic sights on. When i got done i was looking down the barrel admiring the sights when i noticed the barrel looks like it curves to the left drasticly! The top of the reciever is drilled and tapped and it looks like if you had a scope mounted it would be facing way right according to where the end of the barrel is pointing! I haven had a chance to shoot it because it is raining and they are calling for it tomorrow also. Could this be my eyes playing tricks on me, is there a way i can check to see if it is infact straight the way its supposed to be??.
