Put the scope on the gun, in the mounts loose
Place a level on the breech of the gun, when the gun shows level look through the scope and line up the cross hairs with the string, which will be straight.
Tighten up the scope mounts and you're there
I try that,but when i do that,reticle is match with string,but then my scope is lean to the right,you can see with eyes that it is not straight.
I repeat the reticle can be at buble level,but body of scope cannot be.
