Umarex regulator from 1 bottle to another

Rob,
Airgun Detective's video for upgrading original Gauntlets to larger bottles should prove helpful. Pretty sure the regulator threads are the same, but PSI output varies. I did the upgrade on my G1 .25, went with a 2100psi regulator (same PSI as G2 .25) to replace my original 1900psi. Both regulators threaded into original bottle and new larger one. WM
