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.
