Along with the release of the Krytac Trident PDW M4, they released the stock as an individual item. It features ample room for buffer tube LiPo batteries under the rear cap, which can be removed with the included allen key, and comes with a rear sling adapter plate. The stock, when collapsed, is just under six and a half inches long and, when extended, is just under 9 inches. This makes it ideal for compact M4 builds where you may be forced by other stocks to move the battery to a new location or wire it to an external battery box, such as the similar stock from the VFC 416c.
