what size allen is needed to adjust the Spyder MR2's velocity adjuster? thnx
PLEASE, dont suggest using what came with the marker or buying a 27 allen set. Looking for someone who knows what exact allen, metric or English, is needed for the velocity adjuster...

its called read you manual, or just look though it,

i looked though the online manual and i didnt see anything about it saying what size you need
