What is your best trick to getting perfect scope alignment when mounting it to the weapon?  My crosshairs always seem to be canted.

Level your rifle first with a bubble leveler, then tie a string with a plumbob some distance away for your vertical reference (just far enough so that you can see it clearly through the scope), line up the scope's vertical crosshair to this string, done! (be sure the rifle remains perfectly level during this procedure by placing it a vise or rifle support.)

Probably not the most precise method, but put the muzzle on your shoe/toe and look at the cross hairs from that distance. Its easier to see mis-alignment that way. (be sure its unloaded!!)

We use two common string levels, (I like the metal Stanley's and clip the string hooks off mine) sold at any hardware store.

Place one on the top flat portion of the elevation (cover removed) turret and place the other on the top of the upper receiver on the AR, (note: for Rem 700 remove the bolt and use the flat area at the rear of the receiver).

Level the rifle in a benchrest set-up, then level the scope to the rifle, nothing is easier.

Suspended string method also works well.

Canted? It doesn't look canted to me!

And when it's mounted, take the vertical level line, and reun the up-down turret, make sure the crosshairs stay parrallel (Spelling?).
Then , you can take it shooting, shoot group of 3, go 4 clicks up, shoot 3, four clicks right, shoot 3, four click down, shot 3, four clicks left, shoot 3. Shout be back at initial group, with nice square of 4 groups.!
