I recently received the new S200s Viper Nerf Pistol made by Zhen Wei Qi (ZWQ) sent from the retailer Zhenduo Toys.

Out of the box it shot a mere 100fps over the chronograph. So I upgraded it!

In this video I show the upgrade I made, discuss the blaster and how it works, and then put it through a chrono test and accuracy test.
