My father recently passed down a Springfield Armory M 14 with composite black stock to me, along with a 1st Generation Government scope on it. While in the Marines I used the M 16 an admit that I have almost no knowledge of the M 14 weapon, however while doing some research on the scope I came across some odd pictures on the internet of the scope. While looking through the scope, the two "hills" at the bottom of the scope should align perfectly with the vertical portion of the cross hair in the center. While looking through the scope I received, the vertical portion of the cross hair is approximately two thirds to the right in between the two hills. This is only the case when it is on low magnification, when it is on high magnification it aligns perfectly. Is there a reason behind this? Is it some sort of range finder function, and if so what is the purpose? Any help is greatly appreciated!
