This single point sling attachment replaces the collapsible (4 or 6)
position butt stock retaining plate. Can be assembled as either a left
or right handed attachment. The sling attachment plate allows the use of
a single point sling to be hooked into the provided loop, allowing the
weapon to be worn on either the right or left side. The plate also
allows the standard sling to be attached to the front sling swivel
without affecting sling length when the stock is collapsed. It is
constructed of carbon steel with a black-oxide finish.
