Spacer for the Nerf Zombiestrike Dreadbolt. Made as a removable piece for adding tension and launching Nerf arrows up to 120'. Slides into existing holes in the blaster shell and bow arm assemblies.
You will need to remove the "lock" that normally holds the bow arms in place. The added tension is more than enough to keep the bow arms in place during use.
This is Version 1. Feel free to improve upon it if you like!
