Hey Ive set this sight up on my bow, and Im very gentle with the allens, however I just looked at the instruction and they say to use a very uncommen 6/32 allen key for the micro pin adjustments. I believe Ive been using a 5/32 thats on my archery switch blade style wrench set. Where can I track one of these allens down, looking like E bay. Local tool stores and tool trucks didnt have it/ cant get it.
