Hello all, I just purchased my first acog and I have yet to take it to the range to zero it. It is a ta31 rco m4 variant on a colt le6920. Does anyone know if it is true or a myth that tapping on the turrets after each adjustment saves ammunition when zeroing? I have heard that it can be a long day at the range if this routine is not followed, kind of like chasing your own tail. I am not familiar at all with this type of "combat" optic ,but have heard once you get used to it, everything else will be lesser than.Any and all opinions would be greatly appreciated, thanks in advance for your time.
