Sadlak Mount Help

I have a Sadlak mount installed on a scout.
With the scope set to mechanical zero impact is about 2.5ft high and and 12in right. Using Burris Z rings with posi-line inserts I can get pretty close, but I still use up almost all of my adjustment.
I've reinstalled the mount with the same results.
Groups are consistent and poi moves predictably, so I don't believe it's a scope issue.
Checked the groove using the Sadlak inspection kit and it appears in spec.
Read directions multiple times.
What are some common mistakes made with this mount?
Any suggestions are greatly appreciated.
Currently going to try to use 2 , .020 posi- line inserts to see if I can get it zero'ed.

Call Sadlak and ask them to send you one of their measuring kits for $5, it comes with some pins and instructions for how to measure your receiver.

Record the measurements on the form that came with the kit and send it to Sadlak, they will either send you a mount that will fit YOUR receiver or will modify your mount to fit.

The problem with fitting a mount to a SAI rifle is, the receivers are not made to USGI specs.

The folks at Sadlak are quite familiar with this problem and will be happy to help.

Thanks from Rich D

I see you have used the Sadlak inspection kit and it gauges fine, and re-installed the mount to confirm. How about the rings? I'm assuming you checked for proper fit and alignment on the rail?

The rings you are using aren't some long range rings with 20MOA built in are they? That may explain some of the extreme vertical offset you are seeing...

Installing Sadlak Mount

I installed a ARMS 18 on my SuperMatch.

I believe the Sadlak and the ARMS are similar in mounting technique, so my experience may be relevant to your problem. My first time out with the new mount, my rifle shot high, right.

As I recall, the clearance required between the mount rail and the stripper clip guide is .004+ (at least for the ARMS mount).

My rail made contact with lower half of the clip guide, which was difficult to see. I discovered this using a feller gauge.

I removed ~.010 off of the rear end of the mount to obtain the clearance necessary. After the "mod" mount lined up perfectly.

A little cold bluing on the sanded area ensured rust protection.

Thanks from dbb1776

This is the second set of rings. The first set had the same problem. I decided on the Burris rings because they offer the ability to shim the scope.

This seems like a possibility.

Make sure you adjust the set screw on the front of your mount BEFORE you tighten everything up. I had the same problem, I adjusted it in the correct order and rthings are fine now.
