Just my thoughts on it having done lots of manufacturing rework on bad parts. Here in the US the Blaser retailers have to stock so much of each part. They then take their “tinker toys” and package them per the customer’s order. If they did not stock enough PH plastic stocks, then they would either have to tell the customer to wait six months until the next order came in (thus possibly losing an order), or rework one of the existing stocks they had around.
Thus, One Day... I suspect yours was a rework in order to not tell you it would be six months until you got your rifle and them losing you as a customer. Possibly they have an “in-house” so called gunsmith who does the rework, or an “ out-of-house” who claims to be a gunsmith.
Sadly not all gunsmiths have the same skills.
JMT on a possible reason for the difference.
