It looks to me like the rear pic rail is the wrong way round and is overhanging the ejection port. Suggest you set up the scope rings on the FX Impact rail then try the 223 mounts in various orientations.

If I spin it it will then stick out off the back of the action? It won’t make a difference as long as it doesn’t catch on anything but still not perfect.
It could just be that they are “weaver” rails and “picatinny“ mounts, the sizes are similar but not the same
