Windham Weaponry’s MCS Multi-Caliber “Bug-Out Bag” System is packed into a high quality back pack that we offer for any number of camping and travel uses. This fine compartmented backpack includes a generously sized zippered pouch on the outermost back, then two zippered, full size layers. The largest compartment is shown open in the 2nd photo (sorry – receiver & barrel assembly are not included). The pack is constructed of a Lightweight Nylon Shell and 500 Denier Nylon interior for maximum durability. The interior accepts Velcro attachments for usage flexibility. Padding in areas that rest on the back makes for a comfortable carry. Sturdy Shoulder Straps & Waist Belt will provide years of hard wear use, and numerous Fastex Buckles and Cinch Straps are adjustable to fit any load you want to carry. An adjustable weapon tie-down system is included – its velcro attached components are easily re positioned for flexibility. Pack dimensions are 25″ H x 12″ W x 9″ deep.
