Gents,
Powder Shot II, Training Grenade will be released very soon. Powered by CO2. As loud as XMPB4. (.22 Caliber).
No bearing design. 2 valves lucking mechanism. Precise timing delay.
Re-usable. Non-explosive. Make huge sound only. However, you can play it as XM-PB4. (fill it with powder...)
Best Regards,
Mad Bull Airsoft

Looks interesting! I'd like to see a demo video of it though.
