The ACS Carbine Stock offers expanded storage for extra batteries, small parts or gear and includes a lengthened, widened cheek weld for comfort. Water-resistant storage tubes along the cheek weld area hold up to three CR123A or AA batteries each. An additional storage bay near the butt-pad is accessed through a latching compartment door on the right side of the stock. The ambidextrous release latch and friction-lock system provide quick, dependable adjustments that lock down tight and keep the stock in place during hard use.
