you are wrong now you have been corrected
and this method will work on any target sight that has a third axis
only thing is if you are using a threaded pin will require a torpedo level.
this is the cheapest and easiest way to level your third axis to your bow
now if you want to get out your wallet and buy a leveling block hey that is OK by me but the way I mentioned is as accurate and works just as good.
