The ultimate stock for your rear-wired AEG! The Krytac Adjustable battery stock can house three different types of batteries at the same time! A nunchuck style battery can be housed in the crane-stock style tubes, a stick LiPO battery fits in the buffer tube, and a small brick lipo can be stored in the very rear of this stock. The battery compartment is much easier to access than standard crane stocks. Simply press the buttons on the sides of the stock and the butt-plate comes off. The butt-plate is rubberized and textured to keep a solid grip against the shooter's shoulder when firing. A QD sling attachment point can be found on both sides of the stock. The stock adjustment button is easy to access and has been recessed into the contour of the stock, keeping it from snagging on clothing etc. This stock comes standard on several Krytac AEGs, but can also be used with other brands.
