Sightron Scope

[Seabeeken]

Since Leupold has dropped the competition line and closed the custom shop I had to fine another scope to use in UBR. Several shooters recommended a Sightron S3 Competition scope for my rifle. It has .1" clicks so I thought I'd try it. Well, I bought one, new and once installed I noticed the crosshairs were tilted left. I rechecked the scope level and it was dead on. I had some load testing to do so went with it. With each shot, the crosshairs tilted further and further to the left and eventually was an X. Contacted Sightron who said ship it back for repair, which I did. It came back a week later and it was installed once again and leveled off the turret. Once again the crosshair was tilted left exactly the same amount. At least this time it didn't rotate further. I am contacting Sightron once again. I wont be buying another.

I never level off the turret.
Some use a plum ball line....
In my shop I used a 4 foot level and drew a lateral line on the back wall.
Tech at Leupold said the same thing, they do not recomend using the turrets.
Hope this helps

I'll bet they will replace it or refund your money. They have always given me those choices and have done their best to work with me. They do make a good scope and they track very well. Tell them you want that scope replaced or your money back.

I mount a lot of different scopes for folks these days in various brands. The reticle not being symmetrical to the turret unfortunately is fairly common. I mount with a plum line and the rifle leveled. For what it's worth I like Nightforce a bit better but I won't be getting rid of my Sightrons.

I use a plumb bob line to line up the reticle.

Same. I level the rifle then I hang my plum line on a 4 X 4 piece of white paper on my 100 yard target and align my vertical crosshair. I mounted a scope just last week that the left leg of the horizontal crosshair out of wack.

Sightrons are great scopes. That said...
If you dial - set vertical off the turrets.
If you holdover with the reticle - set vertical off the reticle.
