As its name suggests, it is meant to be an extension of the Hail-Fire. The kit is designed to improve the capacity of the Hail-Fire, which does not come packaged with as many rounds as it can handle. With the stock blaster clips and this upgrade kit, the Hail-Fire has a capacity of forty-eight darts. Although it says on the box that it is for the Hail-Fire, it can be used for any Nerf clip system blaster.
It was first discovered in July 2012 on an Amazon.com listing.
- Strangely, there are no Hail-Fire Upgrade Kits that come packaged with the clear variant of the six dart clip that come with the Sonic ICE Hail-Fire.
