So you are preparing to take on an army of zombies in the near future? You are going to need weapons that can do the job. The AK-47 Rifle With Chainsaw is an AK-47 rifle with an attached chainsaw:
The DoubleStar Zombie-X AK-47 is a weapon specially customized to battle zombie hordes by attaching a battery-charged chainsaw to the end of the barrel, as well as a EOTech Zombie Stopper XPS2-Z Holographic Sight which puts a biohazard symbol on your target instead of the classic red dot. DoubleStar hasn’t announced when or if this will go on sale, but its less fancy DSC Zombie Slayer predecessor sells for $1,249.99, so the Zombie-X is likely to be a bit pricier.More gadgets like this: here
