With the post-apocalyptic-DIY aesthetic of NERF’s Zombie Strike series, I suppose it was only a matter of time until a blaster modeled after a nailgun would be introduced to the line. However, the Nailbiter, as it’s called, actually happens to be one of the cooler blaster designs to come out lately. Requiring “no priming” / chambering of a dart, the Nailbiter feeds from an 8-dart “vertical indexing clip” which feeds upwards as it fires (see below video). The blaster is compatible with NERF stock and barrel extensions that work with other N-STRIKE and Zombie Strike blasters, and an accessory rail on the bottom of the blaster allows for the attachment of additional accessories.
You can pick this one up wherever NERF blasters are sold.
