Try to point your toes outward and relax your ankles so your heels will rest on the ground. Relax the weight of your upper body forward onto your left arm.
(4) For ranges greater than 150 meters, lower the buttstock of the weapon to obtain the proper sight alignment and sight picture.
Grip firmly to prevent this from moving the weapon from your shoulder pocket.
WARNING: Make sure the sling is clear of the weapon muzzle before firing.
