Abstract: A sling assembly for a rifle, shotgun, or similar firearm consists of a butt portion (1) of the stock of a rifle, a rear or first multi-directional swivel (3) which is pivotally attached between the toe and the heel of the same butt portion of the stock of the firearm, a fore-end portion (2) of the stock of the same firearm, a front or second multi-directional swivel (4) which is pivotally attached to one of the two sides of said fore-end portion (2) of the same firearm stock, and connected to the rear of the first multi-directional swivel (3) and the front or second multi-directional swivel (4) is a sling or strap (5) whose length is adjustable. A firearm equipped with this sling assembly can be carried conveniently in various ready-to-fire and well balanced positions without tiring the arms of the person carrying the firearm and can be fired quickly with considerable accuracy since the first swivel (3) guides the butt (1) to the correct point of the shoulder.
