Any one with the instruction can email me the softcopy?

I am new to scope alignment, i have done it on a lighted retical ep, but this one i needed some help.

With the retical absolutely adjustible, how does it help to align the scope.

The reticle is not centered in the first place...why? and very difficult to centralised.

thanks for any help!

Hi,

It don't come with any instruction, but it quite easy to use. There are two screw that adjust the reticle in x-y position and the battery compartment act as the adjustment for rotation of the reticle when the screw above the battery compartment is loosen. See the below website:

IMHO, it is better and easier to use than fixed reticle... especially for drift star alignment. The basic idea is that you don't need the star to be in the centre. You bring the reticle to the star... the rest is same as normal fixed reticle.

Have a nice day.
