Thanks to Mr. Qiu Fan for his modified Fangqiong

Thanks to Brother Kuang Xiao Chong Feng for a lot of help with Nerf blasters

During use of the Fangqiong, the foregrip often made me uncomfortable, especially with such violent performance. Following Brother Kuang Xiao Chong Feng's suggestion, I printed Pyrangle v5, but found the fit was loose.

This inspired me to improve this foregrip for Ontos and Fangqiong.

The improvements are now complete, it is very comfortable, and the thumb that had no place to rest has found its home.

Further improvements will be made based on your feedback.
