This is a genuine US military surplus spare barrel bag designed for the M240 Bravo or M249 SAW. This case measures approximately 30" long. The exterior of the bag is made tough to withstand water and abrasions. The interior pocket of the bag is lined with a thermal barrier to insulate a person from the hot barrel. The shoulder strap is detachable and measures approximately 22" long by 3" thick. 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!
