muzzle of the rifle to pass through. The other side is simply a straight section.
The scabbard is made of fiberglass and painted green. The throat has a metal piece with the markings USM8. This
section has two metal lips facing downward. The tip has a hole where the leg strap would be located. A canvis flap
is found above the fiberglass section. This flap acts as a belt loop and also secured the wire hook that connects the
