Should be smooth shank on the lower side to the cap screw. Maybe the rear screw is captured as well, and is inside the stock body up inside the rear screw hole? I don't own an echo, just a low of experience with every other Tikka krg option.Thank you that’s very helpful. Is the rear action screw all threads or is there any smooth shank?
Edit, no the rear isn't captured. Screw should be included, call KRG or the individual you purchased from. Item was likely left out or lost.
See in below photo the machine cap screw and washer.
