The USB42 (Urban Sniper Bag) is a modern tactical rifle backpack specifically engineered to support professional operators in urban environments, and features a unique zip-open design that allows the USB to be transformed into a full sized shooting mat with integrated bipod stops. A 15mm layer of closed cell foam between the inner and outer shell protects your rifle when you're on the move, as well as increasing comfort when deployed on concrete or asphalt. Internal lash points and bungee tie downs keep your rifle secure, and a water resistant outer shell and a polyurethane back coating keep your gear clean and dry at all times. The 5.11 yoke backpack straps distribute weight evenly and can be removed and stored in a dedicated pocket, while heavy-duty grab handles allow quiet handling when lying prone. A front compartment provides plenty of room for magazines, optics, or additional accessories, and features a web platform and compression straps for customizable storage and secure carry. A Flag holder and WriteBar allow quick ID, and genuine YKK zippers and Duraflex hardware points are used throughout to ensure maximum durability and reliable action. Material: Polyurethane.
