Burris Signature Pos-Align rings. Simple and cheap solution. Or you could shim the base up in the rear to gain you some elevation. Mechanically recenter your scope and start over.

Just wondering, how much total adjustment does it say your scope has?

[dtbighit]

I'm not sure how many clicks or moa it has I didn't count and it does not say in the generic instructions,there seem to be lots of clicks but they are only 1/8 moa

OK, who's scope is it? They might list it on there website.

[dtbighit]

There are 306 clicks of elevation,at 1/8 moa per click

[jmg8550]

Ok, so you've got roughly 40 MOA total adjustment. That's not much considering it's only a fixed 10X scope. That means you have 20 MOA up or down from optical or mechanical center. Are you using a one piece AR scope mount or rings?

[dtbighit]

So 306 clicks at 1/8 should be a total of 38.25 minutes of elevation?

Correct.

[dtbighit]

It's actually 10x40x56 and its on rings
