RGB Crescent Suppressor Details
The RGB Crescent is a hybrid silencer designed for 9mm and 300 AAC Blackout subsonic ammunition.
To date the Crescent is the most advanced 3D printed suppressor (or silencer) allowing users to reduce noise output from their firearms for under $250 (this includes the tax stamp provided courtesy of the ATF).
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.

Over the course of development, I learned a lot of neat and interesting tricks for FDM printing optimization. For example, the Crescent breaks hard with current guncad silencer trends, and is printed entirely vertically without supports. It’s also where it gets it’s name! pic.twitter.com/GedPHPfe1w

You can dump 9mm supes like an absolute champ through it. 9mm subs are dead silent, and it can just lay down 300BLK Subs like it’s no issue. This video is from a beta tester testing 300BLK subs for he first time. Unfortunately, it does not appear to handle 300BLK supes (yet) pic.twitter.com/c9fa9Sbg0F
