[SThunderTV]

To get more range and power from S-Thunder's M203 grenade shells, players can do the following,
- fill shell with BBs
- then fill it with water
- seal the grenade shell with packaging tape

The following demonstration from RedDragon Airsoft shows this process using CO2 in their video,

The tape will help maximize the pressure of the gas before the bbs and water is released and the water will help carry the bbs a much further distance.
