We wanted to make a cheap solution for locking rings on hopups. This design was created using 3D printing using engineering grade materials specifically Carbon Fiber Nylon. A material difficult to print, but extremely strong.

Plus we wanted to make it cheap and affordable!

Fits in all major hopup units, and can be utilized with our Hop up O-ring spacers.
