DBoys M4 Folding/Extending Stock
One of the best things about the M4/M16 series of guns is the ability to change out virtually every single part to your hearts content, customising your rifle to how you use it, and more importantly how you want it to look. Typically speaking you will see two main stocks on an out of the box gun; the standard crane stock and the LE stock. These are not exactly to everyone's tastes, and you can be limited in what options you have, especially concerning battery space. This is a problem that DBoys have meticulously tackled with their Folding and retracting Stock. This stock is constructed out of high quality metal, however there is no battery space in this stock.
