Expect ...

Build a crap junk custom rifle and send it to the customer ... customer asks nicely to have it made right.

you opened up one helluva can of worms.
simple as that... not only have an unhappy
customer , got one that has now been Kicked...
again.
That is not good customer service ...
not in any twisted universe.
