Designed by the late RubyGB, a talented and valued member of the 3D printed gun community, the RGB Crescent was intended to be a continuation of Jstark’s work by bringing suppressed firearms to anyone – anywhere in the world.

First and foremost, I would like to thank jstark1809 for inspiring me in the first place. Though he may be gone, his spirit still lives and fights on.
