A friend of mine was just inspecting my Inrange bulgie 74.  As he was checking out the rear sight, he lifted it up and rotated it all the way forward and now it has no spring tension. He feels really bad like he "broke it" and is very worried about it. I told him it was probably something I could easily fix.

Is this something I can easily fix or will I have to take it to Troy at Inrange?  

Thanks for any help.

It sounds like the spring has just moved out of position.

Thanks for the reply.  That's what it looks like to me, the leaf spring under the sight got popped out of position.   I just don't know how to fix it.  

You will see a small detent in the rear of the spring,move the spring rearward until it locks back in position.
