This is a quick prototype (2) piece design for maybe the most underrated rival ball blaster. pump action and now 25+ round hopper. 100 fps. $14.99!!
The hopper is 196mm and prints supportless vertically, larger side down. I already had the magazine section fabbed up from a previous nerf rival mag STL i made. just added the lock.
It has a quick load open top slot which lets balls in but not out. Im not sure on final capacity but should be well over 25rds.
have fun!
