ProWin CNC GBB M4 Magazine CO2 high pressure test - YouTube

1. That's not a prototype, it's a stock v2 Prowin mag

2. It's for the WA system not WE

3. The footage shown was a test to show how much pressure a PROWIN mag can stand up to, not intended as any sort of proof of concept for players to start loading CO2 directly into mags.
