Grays:
One must use a Marlin 60, birch stock, with pressed in squirrel on the stock, with a serial number ending in even number, and the number "2" is historically proven to be more effective than other even numbers.
Best loadings are Win X22LR, CCI Mini-Mags.
Reds:
One must use a Ultimate Extreme Enhanced Operator Ruger 10/22, this is the one requiring the black market selling of MIL.
