So after I ordered my tang sight, i went ahead and inspected the pre drilled and tapped holes on the tang of the reciever. The plug in the first hole came out with some effort, however, the second hole looked like this.



so as I was curious, I took off the stock and it appears that the screw holding the safety mechanism in place is using the same hole from the bottom? Is this normal? Once I mount the sight, will there be enough thread in the second hole to hold the screw? Will I just have to shorten one of the screws?
