Scope not parallel to bore

[d_striker]

I mounted my scope on my SPS Tac AAC SD a couple of weeks ago. I noticed then that my scope was "cross eyed" and pointing slightly to the left.

I didn't think much of it then as I'm fairly new to long range shooting.

I'm not sure if the receiver holes weren't milled in line or if the EGW base is off.

What's the best (and cost effective) way of fixing this and getting my scope parallel to the bore?

Adjustable windage rings?

Well the first place to start is with the rifle. We need to make sure the mount holes for the base are axially aligned to the bore. If they are GTG then checking the base is the next step.
Were the rings aligned before mounting the scope?
Using adjustable rings is an absolute last resort.
How did you ascertain the scope is not aligned?
Has the rifle been bore-sighted?

I'm at work now and plan on taking it apart to examine the mount holes.

I don't have any scope alignment rods and was just excited to slap everything on, zero at 100, and shoot a match.

The axis mismatch is so severe that you can see it with the naked eye. That and I had to dial quite a bit of windage to get it zeroed.

What rings are you using?

[d_striker]

Burris xtr's.

The rings are good. It's either the base or mounting holes.

I thought the same about my set of xtr's. Turns out they were off center. A different set of rings was just fine. I've seen this same issue with three other sets of xtr's in the last couple weeks. Might be worth it to really look them hard. Mounted on a one piece base you could see mine were not in alignment. Hope maybe your set is better than mine was. They are going back.
