My F3 came with 2.0" of drop at the heel. Have spent quite a bit of time and money sorting this out. Through various means, it now has a 3" drop at the heel. As a result, my head is now up, and I can see better. Also, there is Zero (0") (nada) cast on the stock, which has also been sorted out. I have yet to figure out why Blaser has such unconventional stock dimensions.
