Doublestar showed off their Zombie X Chainsaw Rail Attachment at SHOT Show 2012. It attaches to a Picatinny rail with the power button on the left hand side. It is powered via a battery pack mounted onto the rifles stock. If you look closely at the picture above you can actually see it’s a fully functioning chainsaw. While the Zombie X chainsaw was a project for SHOT, Doublestar may bring it to market. Stay tuned for more info as we get it.
