Hey all, hoping someone can help, or have seen this problem. Took a CASM mount to my gunsmith for an install, and he just called me today with a problem... wondering if you've seen this before. Apparently the sight pocket on the Norinco receiver is off for windage, and the CASM while sitting snugly would sit pointed at an angle for windage. Anyone encounter this before? I'm sure he can machine it to sit properly, but if anyone has any advice on what to do here, that would be great.

There have been a few posts in the recent past about out of spec sight pockets. It might be worth the time to do a search before any metal is removed. Dig into the M14 sub forum and you should find some information.
Thanks, I did some digging and the sight pocket is probably out of spec. My smith tells me it's skewing left hard. Seemed like solutions were to get rings that fit or remove metal, and I'm not.... particularly tied to this receiver. Honestly it's the last Chinese part on the rifle (most everything is USGI now)... if removing metal from it will make things fit, I'm game. Worst case scenario is something goes horribly wrong (doubt it) and I have to save up some more paycheques and buy that LRB receiver I've been lusting after. Then I'll have a full Chinese rifle of parts to put back together, haha.
I talked to Frank at M14.ca and he was very helpful, and gave me some things to look into. So, for most people who run into this problem, you can probably fix it without having to remove metal. The first solution was to tighten the right screw first in a way that aligned the mount to the inner wall rather than the pocket, but we tried that and cause it was so snug, no luck. Second was to shim, but it's a tight fit, so no shimming can be done without removing metal... so I gave my smith (Jason at GunCo... He does very good work) the go ahead to remove metal.
In future I don't think I'll be buying any Norinco products as long-term projects, it's sooo much easier to start with something that will be in spec and to swap things out than have to have someone who's competent enough to remove metal do it for me. Learning experience, for sure. (but it's been a fun one) I should stress there is absolutely nothing wrong with the CASM mount itself, that thing is super well engineered and Frank got back to me in hours and was super helpful. It's the Norinco receiver that's letting me down.
