Ok, call me an idiot but, I have several military rifles, and most have two sets of upper sling mounting hooks or whatever you call them. Like the Garand has two, the M1A has two, I think the Smith Corona has two, etc. These are where the sling wraps through and these rifles have two sets on the upper part of the stock.
What use does the second sling hook have, or is it just an option to use one or the other?
