The M1956 butt pack was made from OD7 cotton duck and featured a small carrying handle, a plastic cardholder and side webbing for attaching standard slide-keeper fixture equipment. The pack also had a row of eyelets on the compartment flap that could be used for attaching hook fixture gear, such as a machete sheath or a bayonet scabbard.The pack was typically worn on the back of the pistol belt, though it could be worn higher up the back with the use of adaptor straps. When worn in the standard position the rear suspender straps were clipped directly onto the pack, rather than to the upper row of eyelets on the belt.
