The Battlelink Utility Collapsible stock is a drop in replacement for the standard M4 m16 buttstock. The stock has a very large rear storage compartment and two quick-detach (QD) sling mounts are positioned on the front and rear of the stock body for sling attachment. The shape of the upper stock provides an improved cheek weld over the standard M4 buttstock.
The choice of stock if you are looking for as much space as possible and still want a streamlined design.
