@Escalante11 a larger design would be quieter, but it would also increase cost compared with the current .22 model and the price would be in line with the Zero Gravity. The 6.5 will work very well on a .223, and honestly this suppressor already sounds great on a .223.
We’re testing Saturday: we’ll run the .22 prototype and the 6.5 Zero Gravity against an Ultra 7, OG, SilencerCo Harvester, AB10, and possibly an Ultra 5, and we’ll film the results. For shooters who want something slightly larger than the .22 but still optimized for a .223, the 6mm Zero Gravity will be the ticket (Spring 2026).
