That is one of the reasons I don't want to go with the Chipmunk or Crickett....I don't care for the pull knob to cock..or the fact that it's not drilled and tapped....
Both the chipmunk and cricket are drilled and tapped for their scope mounts. For an additional $15 you can buy the base off of their web site. I don't mind the cocking piece knob, as that is what I learned on with my Dad's old single shot .22 lr when I was growing up. The knob didn't seem to bother my daughter either, and she learned to manipulate it quickly. The ascetics of the knob doesn't seem to bother as many kids as it does their parents.
