Rival Thumbscrew


6 in stock



Does not work on Zeus! Works on Nemesis, but not perfectly, please read description!

Finally a thumbscrew option for most Rival flywheelers!  This is an M4 thumbscrew that will fit the following Rival blasters:

  • Hera – Almost perfect fit
  • Khaos – Really good fit, a little long, so it makes a cracking sound on the last turn, but doesn’t break anything important.
  • Nemesis – Slightly too short. Does not engage with threads on the blaster, but keeps battery door from sliding back.

Sold Individually.

Blasters should be modified at your own risk by an adult or with adult supervision. Modification of blasters may increase wear and reduce lifespan of blaster. Always wear eye protection. Never point at someone’s face. By purchasing, you agree that FoamBlast is not responsible for injury or damage caused by misuse or accidental usage.
