KIDD Aftermarket Receiver Scope Base With Fitted Slot

These scope bases will mate with the slot cut on the KIDD Classic or Supergrade receiver models. The greater the minute of angle or MOA the farther the customer can shoot. The theory being that a 20 MOA scope base will slightly cant your scope downward, so when you "zero" your rifle your barrel will actually being pointed upwards which is helpful for a .22 rimfire trying to hit a target past 100 yards. This increased MOA scope base may not be necessary if your scope has enough vertical adjustment.
