Green scopes were 1st issues . It’s for sure this is an armor rework . Mount looks correct . Scope doesn’t , I have never heard of M40 with that model scope . I have 3 clones myself . You could have built all three of mine for the cost of one at CMP . Best of all I can shoot mine and not loose any value . Mine are worth nothing to anyone , but me . But they sure are fun to show off and shoot . I have 2 walnut stocks remaining and a few sets of mounts and rings I have collected awaiting another build .
