Disco is stock except for the Maurder trigger group, the MellonAir spring adjuster
and the TKO Muzzle Brake.

Fill pressure starting at 2200 psi.
#1- 8 turns in from flush, end pressure 1200 psi
#2- 7 turns in from flush, end pressure 1250 psi
#3- 6 turns in from flush, end pressure 1400 psi
#4- 5 turns in from flush, end pressure 1450 psi
#5- 4 turns in from flush, end pressure 1600 psi

| Group B is more consistent (less fliers)- so I would suggest using whatever setup was there and working on shooting technique beyond that. |
