This is a genuine US military surplus spare barrel bag designed for the M60 barrel. This case is made from vinyl and nylon and can accommodate a wide range of barrels or even carry short or folding stock rifles. This case measures approximately 29" long. The exterior of the bag is made tough to withstand water and abrasions, and features two zippered compartments. The shoulder strap is detachable. This would make a great range bag for carrying spare parts, a rifle that's broken down, cleaning supplies, or anything else you may need at the range!
Functionally, these bags will be the same regardless of the styles mentioned here. However this is a noticeable difference in color between the two options.
